yep umang is rite........but do u know wat to do after that.......
ill tell u in case u dunno how to proceed...
c whn diff of diff is in gp thn the general term is of the form
A r^ n + bx n + c
u know r = 2
for 1 st term 2A + b + c = 9
for 2nd
4A + 2b + c=16
for 3rd
8 A+ 3b + 3=29
frm these equations u vcan find a , b ,c
and thn find the sum.....i hope ull be able to solve it....in case u hv any prob ur free to nudge me.........
rate me if it was useful
