Question 815181
I see a pattern for the first set in which you take the given number and multiply by 4 and subtract 1, then multiply by 4 subtract 2, multiply by 4 subtract 3, mult by 4 and subtract 4, etc.  Starting with 2, multiply by 4 subtract 1 giving you 7.  Take 7, multiply by 4 and subtract 2 giving you 26.  Mult 26 times 4 and subtract 3 giving you 101.  Multi by 4 subtract 4 giving you 400.  Next would be multiply by 4 and subtract 5 giving 1595.


For the second pattern, I'm not sure.  You might try starting with 7 *3 = 21.  Next, take 8*3^2= 72.  Next, take 9*3^3=243.  This might be a stretch, but it's all I can think of.
