Question

The sum of three consecutive integers is 267. What is the largest integer? (1 point)

Answer 1

x = 1st integer
x + 1 = 2nd integer
x + 2 = 3rd integer

(x) + (x + 1) + (x + 2) = 267 -- combine like terms
3x + 3 = 267 -- subtract 3 from both sides
3x = 267 - 3
3x = 264 -- divide by 3
x = 264/3 =
x = 88 ==>1st integer
x + 1 = 88 + 1 = 89 ==>2nd integer
x + 2 = 88 + 2 = 90 ==> 3rd integer

check..
88 + 89 + 90 = 267
267 = 267 (correct)

Largest number is 90.
