Hi,Hope I can help

\n" ); document.write( "consecutive means \" in order\"(examples: 45,46,47,48 . Sunday, Monday, Tuesday)
\n" ); document.write( ".
\n" ); document.write( "To find the 4 consecutive numbers, we have to find the variables for all four numbers
\n" ); document.write( ".
\n" ); document.write( "Since consecutive means \" in order \"(we are trying to find 4 numbers that come right after the other(example of consecutive numbers: 22,23,24,25,26)
\n" ); document.write( ".
\n" ); document.write( "We can always name the first number of any \"consecutive numbers\" - \"x\"
\n" ); document.write( ".
\n" ); document.write( "\"x\" is our first number, to find the other numbers, we will add \"1\" each time(we are trying to find numbers that come right after the other)
\n" ); document.write( ".
\n" ); document.write( "2nd number = (add \"1\" to our first number \"x\") = \"x+1\"
\n" ); document.write( "3rd number = (add \"1\" to the second number \"x + 1\", (\"x + 1 + 1\")) = \"x+2\"
\n" ); document.write( "4th number = (add \"1\" to the third number \"x+2\",(\"x+2+1\")) = \"x+3\"
\n" ); document.write( ".
\n" ); document.write( "(If there was a fifth number you would add \"1\" to the fourth number \"x+3\" = \"x+4\", the sixth number would be \"1\" added to the fifth number \"x+4\" = \"x+5\", you get the idea)(If you were solving for consecutive odd or even numbers, you would add \"2\" every time, consecutive even/odd number = ( x, x + 2, x + 4, x + 6, x + 8, ...)
\n" ); document.write( "(examples of consecutive even/odd number: 3, 5, 7, 9 : 16, 18, 20, 22))
\n" ); document.write( ".
\n" ); document.write( "Since we are solving for just consecutive numbers, our numbers are
\n" ); document.write( ".
\n" ); document.write( "1st number = \"\"x\"\"

\n" ); document.write( "3rd number = \"\"x%2B2\"\"
\n" ); document.write( "4th number = \"\"x%2B3\"\"
\n" ); document.write( ".
\n" ); document.write( "Now we can replace these variables with the problem, and solve for the numbers

\n" ); document.write( "We will rearrange the equation, so we can add/subtract like terms
