What is the difference between two consecutive even numbers?
\n" ); document.write( "Even numbers are numbers that are multiples of 2.
\n" ); document.write( "You could also say that they are divisible by 2.
\n" ); document.write( "The first one is \"1%2A2=2\" ,
\n" ); document.write( "the next/2nd one is \"2%2A2=4\" ,
\n" ); document.write( "and the 3rd one (the next one after 4) is \"3%2A2=6\" .
\n" ); document.write( "Counting by 2's you get from one even number to the next one.
\n" ); document.write( "2 and 4 are consecutive even numbers, because 4 is the next even number after 2.
\n" ); document.write( "4 and 6 are consecutive even numbers, because 6 is the next even number after 4.
\n" ); document.write( "That is what consecutive means: one after the other as we count then in order.
\n" ); document.write( "2 and 6 are even numbers, but they are not consecutive even numbers,
\n" ); document.write( "because we skipped 4.
\n" ); document.write( "The difference between two consecutive even numbers is \"highlight%282%29\"
\n" ); document.write( "
\n" ); document.write( "What is the difference between two consecutive odd numbers?
\n" ); document.write( "It is also \"highlight%282%29\" , because the odd numbers are in order
\n" ); document.write( "1, 3, 5, 7, 9, 11, 13, ....
\n" ); document.write( "
\n" ); document.write( "If a problem talks about two consecutive odd (or even) numbers, I would start by defining
\n" ); document.write( "\"n\"= the first of those consecutive odd (or even) numbers.
\n" ); document.write( "Then, I would write that
\n" ); document.write( "\"n%2B2\"= the next/other consecutive odd (or even) number.
\n" ); document.write( "If a problem talks about three consecutive odd (or even) numbers, I would call them
\n" ); document.write( "\"n\", \"n%2B2\", and \"%28n%2B2%29%2B2=n%2B4\"
\n" ); document.write( "
\n" ); document.write( "How many consecutive even numbers are there between 35 and 45?
\n" ); document.write( "The last/greatest even number before (less than) 45 is \"44=22%2A2\" .
\n" ); document.write( "That is the 22nd positive even integer,
\n" ); document.write( "the first one being \"2=1%2A2\" ,
\n" ); document.write( "the 17th being \"34=17%2A2\" , and
\n" ); document.write( "the 18th being \"36=18%2A2\" .
\n" ); document.write( "Of the \"22\" positive integers less than 45 (including 2 and 44}),
\n" ); document.write( "\"17\" of them (from 2 to 34) are less than 35.
\n" ); document.write( "The other \"22-17=highlight%285%29\" , starting with 36 and going all the way to 44,
\n" ); document.write( "are between 35 and 45.
\n" ); document.write( "Can we list them and count them to verify?
\n" ); document.write( "Sure we can. They are:
\n" ); document.write( "36, 38, 40, 42, and 44.
\n" ); document.write( "That is indeed \"highlight%285%29\" even numbers between 35 and 45,
\n" ); document.write( "listed in order.
\n" ); document.write( "Are they consecutive? Sure they are.
\n" ); document.write( "They are all the even numbers in order,
\n" ); document.write( "one after the other, without skipping,
\n" ); document.write( "
\n" ); document.write( "How many consecutive odd numbers are there between 60 and 80?
\n" ); document.write( "Just as the first positive even integer is \"2=1%2A2\" ,
\n" ); document.write( "and the 30th positive even integer is \"60=30%2A2\" ,
\n" ); document.write( "the first and 30th odd integers are one less than those:
\n" ); document.write( "\"1=2-1=1%2A2-1\" and \"59=60-1=30%2A2-1\" .
\n" ); document.write( "Similarly, the 31st odd integer is \"31%2A2-1=62-1=61\" ,
\n" ); document.write( "the 40th odd integer is \"40%2A2-1=80-1=79\" , and
\n" ); document.write( "the 41st odd integer is \"41%2A2-1=82-1=81\" .
\n" ); document.write( "The odd numbers are there between 60 and 80 start with 61 and end with 79.
\n" ); document.write( "From the fist \"40\" odd integers from 1 to 79,
\n" ); document.write( "we have to eliminate the first \"30\" (from 1 to 59).
\n" ); document.write( "We are left with \"40-30=highlight%2810%29\" .
\n" ); document.write( "Can we list them and count them to verify?
\n" ); document.write( "Sure we can. They are:
\n" ); document.write( "61, 63, 65, 67, 69.
\n" ); document.write( "71, 73, 75, 77, and 79.
\n" ); document.write( "That is indeed \"highlight%2810%29\" odd numbers between 61 and 79,
\n" ); document.write( "listed in order.
\n" ); document.write( "
\n" ); document.write( "What is the sum of the next two consecutive numbers after 13?
\n" ); document.write( "The number that follows 13 is \"14\" , and after that comes \"15\" .
\n" ); document.write( "The sum of the next two consecutive numbers after 13 is
\n" ); document.write( "\"13%2B14=highlight%2827%29\" .
\n" ); document.write( "
