    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

    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:

    \displaystyle \sum_{r=0}^n r = \frac{n(n+1)}{2}

    So what's the nth term of the main sequence?

    Assuming you meant \displaystyle 2^{n(n+1)/2} then yes.
