Question
Hi Richard, can you help figure out the following patterns:

1/8, 2/7, 1/2, 4/5, ____, ____

-5, 3, -2, 1, -1, 0, ____, ____

1, 5, 14, 30, 55 ____, ____

Thanks so much, need ASAP, figured out all the rest except for these!!!!  Thanks again.

Answer
I'm still working on the first one.
for the second one, the sum of the first two numbers gives you the third number,  the sum of numbers 2 and 3 give you the fourth one, etc, so you have -1,0,-1,-1
for the third one, 5-1 = 2^2, 14-5 = 3^2, 30-14 = 4^2, 55-30 = 5^2 so the next two numbers are
91 and 140
