Let Statement word problems: 3 integers.

Question

Find three consecutive integers, such that the sum of the first and the third is 130.

Answer 1

x-1, x, x+1

x-1 + x+1 = 2x = 130

x =65

the 3 numbers are

64, 65, 66

Answer 2

Let the first integer be X. If we're working with 3 consecutive integers, that means we can express these as:

integer #1: X

integer #2: X+1

integer #3: X+2.

If the sum of the first and third is 130, we can re-write this sentence as the following equation:

X + (X+2) = 130

2X + 2 = 130

2X = 128

X = 64

That means your 3 consecutive integers are: 64, 65, and 66.
