The sum of three consecutive even integers is 42.

Question

Algebraic expression for The sum of three consecutive even integers is 42.

 

Answer 1

We have a, b, and c. Here's what we know:

a = b - 2

c = b + 2

a + b + c = 42

Let's plug in the variable values:

b - 2 + b + b + 2 = 42

Simplify:

3b = 42

Divide both sides by 3, and you'll have b. Subtract 2 to find a, and add 2 to find c.

Answer 2

n + n + 1 + n + 2 = 42

 

Can you solve for n and answer?
