Looks like you're just adding the prior 2 numbers.#2 I'm stumped.  Looks like you're adding 2 more each time.  I don't see that pattern given that it starts with 2,4,9. lbcake PM lbcakeJoined: May 2005Posts: 25459 Hall of Fame #3Posted: 9/3/2012 6:48:39 PM1.  1+2 = 3   3+5 = 8   8+13 = 21  and so on2. The first number in the sequence should be 1. In other words, 1,4,9,16,25,36 etcSquare each number. 1squared = 1, 2 squared = 4, 3 3quared = 9, 4 squared = 16 and so on.
