Every second integer is odd. (The ones in between them are even.)
If you promise that 'n' is odd, then the next odd ones
are (n+2), (n+4), and (n+6) .
We need to add them all up:
n + (n+2) + (n+4) + (n+6) = 4n + 12
Now you're telling me that the sum is 56. Knowing that, I can
figure out what 'n' is, and once I know 'n', I can fiugure out all
four of the numbers.
4n + 12 = 56
Subtract 12 from each side: 4n = 44
Divide each side by 4 : n = 11
The four consecutive odd integers are:
n . . . . . 11
n+2 . . . 13
n+4 . . . 15
n+6 . . . 17 .
Check the answer:
Add up (11 + 13 + 15 + 17) = 56 yay !
