Question

Choose the equation that could be used to find two consecutive integers whose sum is 67.

Answer 1

d) n + (n +1) = 67

1) Let's call the first number as n, and its consecutive as n +1

Then we can write:

n + (n +1) = 67

n +n +1 = 67

2n +1 = 67

2n = 66

n= 33

and n+1 = 34

2) Hence, the answer is n + (n +1) = 67
