Question

Find the two consecutive integers whose sum is at mist 43

Answer 1

21 and 22

Explanation:

Since the integer are consecutive, we can represent them as in and in Plus one. the sum of these two integers is 43 so we can write:

n + (n +1) =43

Open the brackets and simplify.

n + n + 1 = 43

2n + 1 = 43

Subtract 1 from both sides and then divide by 2.

2n = 42

n = 21

(n+1) = 22
