100 is my guess, because the numbers in the sequence do not use the letter 't'

Tracydaks ... Thank you, yea,u r right:)

can u answer this???
100-100/100-100 is equal to 2

Now that doesn't make sense to me lol, I'm still shocked I figured out the first one :o)

8,27,64,125

100..because 'T' doesnt comes in the next numbers...!

1, 4, 5, 6, 7, 9, 11, 12, 22, 34, 62, 65, 70, 71, 105, 113, 206, 249, 284, 371, 402, 437, 551, 601, 613, 727, 1337, 1372, 1681, 1739, 2234, 2437, 2827, 3122, 3641, 3659, 3765, 3943, 4642, 5822, 6599, 7060, 8433, 8557, 9149, 12899, 14322, 15322, 16262, 18117, 23041, 33389, 38676, 39967, 42681, 53125, 60244, 85049, 122771, 193681, 193726, 203005, 219213, 282710, 288212, 359534, 536435, 580866, 591556, 930940

but on a serious note, math and science go hand in hand (even if they aren't always taught as such), so good for you! <br />
