Total number of bricks? This is an arithmetic sequence where a1 = 5, an = 62 and n = 20. The sum to n is given by: Sn = (n/2)(a1 + an) = (20/2)(5 + 62) = 10 * 67 = 670 Answer: there are 670 bricks in this stack. Note also that: an = a1 + (n-1)d So. 62 = 5 + (20 - 1)d 62 = 5 + 19d 19d = 62 - 5 d = 57/19 d = 3 Thus each row has three more bricks than the row above it. or each row has three less bricks than the row below it.

Everyone knows there's a bunch of money to be found studying STEM (Science, Technology, Engineering, and Mathematics), but few fields are as direct about the opportunities for making money as math. 

The tradition of offering mathematical prizes goes back ages. One of the most famous men to offer prizes in exchange for proved theorems is the legendary Paul Erd ő s, whose $25 prize checks were often just framed as a trophy rather than cashed.
