Given a G.P. with a= 729 and 7th term 64, determine `S_7`.

If 3rd term of a G.P. is 324 and 7th term is 64, then find the 10th term.

If the 10th term of a G.P. is 9 and 4th term is 4, then its 7th term is :

The 10th term of an A.P. is 52 and the 16th term is 82. Determine the 32nd term.

The first term of an A.P. is -4 and 10th term is 14. Determine the 30th term.

The 3rd term of an A.P. is 1 and 6th term is -11. Determine its 15th term and rth term.

The sum of first three terms of a G.P. is 7 and the sum of their squares is 21. Determine the first five terms of the G.P.

In a G.P., the third term is 24 and the 6th term is 192. Find the 10th term .

In a G.P., the third term is 24 and the 6th term is 192. Find the 8th term .

The 6th term of a G.P. is 32 and its 8th term is 128, then the value of the common ratio is :

In an A.P. third term is 14 and 8th term is 34. Find S_n and S_(20) .
