+130514 "Guest" might be correct.....it could be the Fibonacci Series......but let's assume that it's a regular arithmetic series....we can find the middle term by finding the common difference, thusly :
8 = 3 + d(3 -1) simplify
5 = d(2) divide both sides by 2
2.5 = d this is the common difference....so....the second term is just 3 + 2.5 = 5.5
And the third term is just 5.5 + 2.5 = 8 as we might suspect !!!
it could be the fibonacci sequence. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... The nextnumber is found by adding up the two numbersbefore it. Similarly, the 3 is found by adding the twonumbers before it (1+2).

This is an "arithmetic sequence", which means the difference between one term and the next must a constant. Since the 1st. term is 3 and the 3rd. term is 8, then,
8 - 3=5 / 2=2.50 appears to be the difference between the terms. Therefore, the 2nd.term should be
3 + 2.5=5.5.........so we have, 3, 5.5, 8, 10.5, 13, 15.50............and so on.
