# in a geometric progression the first term is a and the common ratio is r. the sum of the first two terms is 12 and the third term is 16. a) determine the ratio (ar^2)/a+ar b) if the first term is larg

in a geometric progression the first term is a and the common ratio is r. the sum of the first two terms is 12 and the third term is 16.

a) determine the ratio (ar^2)/a+ar

b) if the first term is larger than the second term, find the value of r
