It is given in the question that x != 1 and x!= -1 ..so how can we use the formula for r1
Same here. How can we assume here r is less than 1. It may be greater than one
How r is less than 1?
Sir how u assume r value less then 1 ,it may be greater then 1 also so that the sum of gp formula will different
