A.M || G.P(nth term & sum OF n terms)

A.P|| nth term||sum OF n term

In a G.P if the first term is 3, nth term is 96 and the sum of n terms is 189, then the number of terms is

Show that the ratio of the sum of first n terms of a G.P. and the sum of (n+1)th term to (2n)th term is (1)/(r^(n)) .

if nth term of an AP is 3n+2 then find the sum n terms.

The sum of m and n terms of an A.P. are n and m respectively. Prove that the sum of (m + n) terms will be - (m+n).

The mth term of an A.P. is n and nth term is m. Then rth term of it is

The sum of the eight terms of a G.P where nth term is 2.3^ n (A) 19880 (B) 19860 (C) 19660 (D) 19680

If the m^(th) term of a G.P is n and n^(th) term be m then find the (m+n)^(th) term

If in an A.P.the sum of m terms is equal of n and the sum of n terms is equal to m, then prove that the sum of -(m+n) terms is (m+n).
