Question 966942
The top level of a pyramid has 1 block Then next level has 3 blocks and the next level has 9 blocks If this pattern continues how many levels are there the total number of blocks is 3280?
----------------
3^0 + 3^1 + 3^2 + 3^3 ... + 3^n = 3280
Convert 3280 to base 3
--> 11111111
= 8 levels
===================
{{{3280 = 3^8/2 - 1}}}
