Question 507499: the sum of two consecutive integers is 78. what are the integers?
Answer by oberobic(2304)   (Show Source):
You can put this solution on YOUR website! Two consecutive integers are not likely to total 78.
I'll show you why.
.
Define the two consecutive numbers in terms of 'x'.
x is the first number
x+1 is the second number
.
x +x+1 = 78
2x +1 = 78
2x = 77
x = 38.5, which is not an integer
.
Two consecutive even integers could total 78.
.
x is the first even number
x+2 is second even number (you add 2 to skip the odd number between the even numbers)
x +x+2 = 78
2x+2 = 78
2x = 76
x = 38
.
so the second even number is:
x+2 = 40
.
The consecutive even numbers are 38 and 40.
.
Done.
