the first two terms of g.p add up to 12.the sum of 3rd & 4th term is 48.if the terms of the g.p r alternatively positive and negative,then what is the first term???? ans is -12. how to solve this???
a(1 + r) = 12

ar^2(1 + r) = 48

dividing => r = -2

=> a = -12

Terms would be a,-ar,ar^2,-ar^3..........
a-ar=12
ar^2 - ar^3=48

Take ratio of both: We get r^2=4
r=2
so, a(1-r)=12
a=12/-1 =-12
