What is the difference between the two consecutive integers whose sum is 55?

Explanation:
Consecutive integers differ by exactly 1, since each next number is one more than the previous. If the smaller is n, the larger is n+1, and their sum is n + (n+1) = 2n + 1. Setting this equal to 55 gives 2n + 1 = 55, so 2n = 54 and n = 27. The two numbers are 27 and 28, and their difference is 28 − 27 = 1. Therefore, the difference between the two consecutive integers is 1.
