Answer:
21
Step-by-step explanation:
Let the smallest of the numbers be N
The other two numbers (consecutive) would be written as (n + 2), (n + 4)
Expressing these as an equation gives : (n) + (n+2) + (n+4) = 69
opening the bracket and collecting like terms, we have:
n+n+n+2+4=69
3n + 6 = 69
3n = 69 - 6
3n = 63
Dividing both sides by 3 or making n the subject formular, we get:
n = 63/3
n = 21.
Note, the other numbers are: 21, 23, and 25
They are all odd numbers
Their sum equals to 69
