Q13 of 110 Page 65

If x, 2x + 2, 3x + 3 are in G.P, then 5x, 10x + 10, 15x + 15 form

Any GP if multiplied with a constant term remains in GP.


x, 2x + 2, 3x + 3 are in GP, 5(x), 5(2x + 2), 5(3x + 3) will also form a GP because a constant term 5 is merely multiplied.


So the correct option is B.
