In a G.P, t₂ = and t₃ = . Then the common ratio is

The sequence –3, –3, –3,… is

If the product of the first four consecutive terms of a G.P is 256 and if the common ratio is 4 and the first term is positive, then its 3rd term is

If x 0, then 1 + sec x + sec²x + sec³x + sec⁴x + sec⁵x is equal to

If the n^thterm of an A.P. is t_n = 3-5n, then the sum of the first n terms is
