Question

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

n + (n - 1) + (n - 3) = 75
n + (n + 1) + (n + 3) = 75
n + (n + 2) + (n + 4) = 75
n + (n + 1) + (n + 2) = 75

Answer 1

last one

Answer 2

consecutive numbers follow each other, e.g 3, 4, 5.... so let the 1st number be x, the next is x + 1 and the next is x + 2.... they sum to 75....
