Question

Consecutive integers are integers that are in order without skipping,.such as 3, 4, 5. Find three consecutive numbers with a sum of 54. Write an equation.
I know the answer is 17, 18, 19, but I don't know the equation. Please help.

Answer 1

The equation is 54=(n)+(n+1)+(n+2)

Which simplifies to 54=3n+3

Subtract 3 from each side to get 51=3n

Divide each side by 3 to get 17=n

Then you substitute 17 for n to get 17 (n) and 18 (n+1) and 19 (n+2).
