"INFINITE GEOMETRIC PROGRESSION. A sequence of numbers in which any number, or term, after the first can be obtained by multiplying its predecessor by a fixed number COMMRATIO which is always less than 1. Example 16, 4, 1, 1/4... or 1, 1/2, 1/4, 1/8... Ans(a) Set INDEX#A=1, INDEX#B=2, N=1, TERM#A=16, TERM#B=8. The sum of the serie is 32. Ans(b) Set INDEX#A=1, INDEX#B=2, N=1, TERM#A=16, TERM#B=-4. The sum of the series is 12.8. Type any key to exit. (c) Copyright PCSCC, Inc., 1993 ||(a) Find the sum of the infinite geometric progression: 16, 8, 4, 2....
