If the sum of three consecutive integers is 69, what are the integers?
Then the three numbers are:
The sum of these numbers:
The sum of these numbers equal
Normally though, my thinking process would be like this:
- Find the mean
- Are they consecutive integers, odd integers or even integers?
- If they're consecutive, +1 and -1 to the mean. If they're odd/even, +2 and -2 to the mean. (Of course it would be different if there are 5 consecutive numbers, 7, etc)
