    35; Although there is never a unique answer for any of these questions, this is the most obvious;

    We have 0, 0+3 = 3, 0+3+5 = 8, 0+3+5+7 = 15, 0+3+5+7+9 = 24, 0+3+5+7+9+11 = 35.

    We can also use the "squaring" hint to see we have
    1^2-1 = 0, 2^2-1 = 3, 3^2-1 = 8, 4^2-1= 15, 5^2-1 = 24, 6^2-1 = 35.

    This is much better as it gives the formula n^2-1 for the nth term.

    we can also do it like this...
    0
    1*1+2=3
    2*2+4=8
    3*3+6=15
    4*4+8=24
    5*5+10=35

    square of no starting from 1+the multiple of 2 in sequence.....
