Answer :

Let the first three terms of G.P. be


It is given that



a = 1


And




…(a = 1)



10(1 + r2) = 29r


10r2 - 29r + 10 = 0


10r2 - 25r - 4r + 10 = 0


5r(2r - 5) - 2(2r - 5) = 0


(2r - 5)(5r - 2) = 0


r =


Therefore the first three terms are:


i)if r = then



ii)if r = then



Ans:Common ratio r = and the first three terms are:


i)if r = then



ii)if r = then
