The sum of three integers is 42. Let x be the middle of the three integers.

I'm confused... what does it mean by the middle? Does that mean the 2nd consecutive integer?

I think you meant to say

"The sum of three CONSECUTIVE integers is 42"

right?

Yeah I think you are right. It's talking about the second integer

(jim_thompson5910) omg yes, i'm sorry!

jim_thompson5910 · Answer

that's ok

jim_thompson5910 · Answer

examples of consecutive integers are 

1,2,3
6,7,8
78,79,80

basically whole numbers that follow immediately after one another

jim_thompson5910 · Answer

if x is the middle, then x+1 is the 3rd number

x-1 is the first number

in general we'll have:  x-1, x, x+1
