Question

Find three consecutive even integers such that the sum of the first and the third is 128.​

Answer 1

9514 1404 393

Answer:

62, 64, 66

Explanation:

I like to work "consecutive integer" problems by considering the average, or middle value. If we call that x, then the problem statement tells us ...

(x -2) +(x +2) = 128

2x = 128 . . . . . collect terms

x = 64 . . . . . . . divide by 2

The middle integer is 64, so the three even integers are 62, 64, 66.
