Question 796269: the average of three consecutive numbers is 26. What are the three numbers? Found 2 solutions by Cromlix, Alan3354:Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Three consecutive numbers:
n, n + 1, n + 2
Average of these three numbers = 26
(n + n + 1 + n + 2)/3 = 26
Cross multiply:
(n + n + 1 + n + 2)= 78
Collect like terms:
3n + 3 = 78
3n = 75
n = 25
Three consecutive numbers:
25, 26, 27.
Hope this helps.

------------
The average is the middle number --> 25, 26, 27

Or,
(n-1) + n + (n+1) = 26*3
3n = 78
n = 26
