Question

when the smallest of 3 consecutive integers is subtracted from twice the largest, the result is 15. What is the middle number?

Answer 1

12?

Answer 2

Let the smallest number be n. then other numbers will be n+1, n+2.
Here largest number is n+2.
2(n+2)-n=15
2*n+2*2-n=15
2n+4-n=15
Find n. Then to find the middle number plug in the value of n in n+1.
