Suppose you go to a company that pays 0.01 for the first day, 0.02 for the second day,
0.04 for the third day and so on. If the daily wage keeps doubling, what will your total
income be for working 29 days ?
~~~~~~~~~~~~~~

The total income will be the sum of the first 29 terms of the geometric progression 
with the first term 0.01 and the common ratio 2, which is

    0.01 + 0.02 + 0.04 + . . . + 0.01%2A2%5E28 = 0.01%2A%281+%2B+2+%2B+4+%2B+ellipsis+%2B+2%5E28%29 = 0.01%2A%282%5E29-1%29 = 5368709.11 monetary units.

Solved.

this is a(1-r^n)/1-r, and r=2, doubling
so it is 0.01(1-2^29)/(1-2)
=0.01*2^29=5,368,709.12
