# Sequences (help)! watch

1. how would i write this sequence in general terms? I tried some stuff out, but im stuck here...

Like for example 2^x, where x = 0...10 etc.
So its like 2^0, 2^1, 2^2, 2^3
2. EDIT: Ignore what I said. I read it wrong.
3. I assume 14 is a typo and it's meant to be 64.

The sequence 0,1,3,6,10,15 is 0,0+1,0+1+2,0+1+2+3,... so the nth term is given by:

So what's the nth term of the main sequence?
4. Thanks, so its just

2^[n(n+1)]/2?
5. Assuming you meant then yes.
6. ok thx
