Question

Choose the equation that could be used to find three consecutive integers whose sum is 75.

n + (n + 1) + (n + 2) = 75

n + (n + 2) + (n + 4) = 75

n + (n + 1) + (n + 3) = 75

n + (n − 1) + (n − 3) = 75

Answer 1

consecutive intergers means n, n+1, n+2
the choice should be the first one.
n + (n + 1) + (n + 2) = 75
