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

you're not kidding right? o.O

Answer 2

firstly, it is the first one...
but if you have a choice use (n-1)+(n)+(n+1) = 75 => that should simplify giving you just
'n'

Answer 3
