Question

11 Answer:

Consecutive integers are integers that follow each other in order (for
example 5, 6, and 7). The sum of three consecutive integers is 417.
Let n be the first one. Write an equation that will determine
the three integers.


12 Answer:
Solve the equation in question #11 for the value of n.

Answer 1

138

Explanation:

n,n+1,n+2

so 3n+3=417

3n=414

n=138

Answer 2

Explanation:

n + (n+1) + (n+2) = 417

3n + 3 = 417

3n = 414

n = 138

so, the 3 integers are

138, 139, 140
