You can put this solution on YOUR website! pieces of candy: n, n+2, n+4, n+6, n+8
n + (n+2) + (n+4) + (n+6) + (n+8) = 200
5n + 20 = 200
5n = 180
n = 36
pieces in each jar: 36, 38, 40, 42, 44

You can put this solution on YOUR website!
The numbers form an arithmetic progression, so the third (middle) jar contains the average number of candies of all the jars.
So the "middle" jar has 200/5=40 pieces.
Then since each jar has 2 more than the previous one, the numbers of candies in the jars are 36, 38, 40, 42, and 44.
