Question

The sum of 3 consecutive even numbers is 78.
What is the second number in this sequence?

Answer 1

Answer: 26

Step-by-step explanation:

1. Make an equation

n+n+2+n+4=78

(You have n+2 because to get to the next even number you'd have to add 2. For example, 2 is even, to get to the next even number, 4, you have you add 2.)

2. Combine like terms

3n+6=78

3. Solve for n

3n=72

n=24

4. Solve for the second number

(The second number would be n+2)\

n+2

24+2

26

ANSWER: 26
