Question

12) Brad wanted to find three consecutive whole numbers that add up to 81. He wrote the equation
(n - 1) + n + (n + 1) = 81What does the n stand for?

Answer 1

the second of the three consecutive numbers.

Answer 2

the numbers are 26,27,28

Answer 3

n = 27

Answer 4

Let n=the first number
Let n+1=the second number
Let n+2=the third number

n+(n+1)+(n+2)=81
n+n+1+n+2=81
3n+3=81
3n=78
n=26 This is the first number

n+1=26+1=27 This is the second number

n+2=26+2=28 This is the third number

Therefore, the three consecutive numbers are 26, 27, 28
