Given three consecutive integers with a sum of four times the second number, write an algebraic equation for this situation

Define x:

Let the first number be x.

1st number = x

2nd number = x + 1

3rd number = x + 2

Construct equation:

x + x + 1 + x + 2 = 4 (x + 1)

3x + 3 = 4 (x + 1)

Answer: 3x + 3 = 4 (x + 1)
