Each term of an A.P. is doubled. Is the resulting sequence also an A.P. ? If it is, write its first term common difference and nth term.

The terms of a G.P. with first term ‘a’ and common ratio ‘r’ are squared. Is the resulting sequence also a G.P. ? If it is so, find its first term, common ratio and the nth term.

For A.P. -5, -1, 3, 7, write first term ‘a’ and common difference ‘d’ .

If a_(1)=1, a_(2)=5 find the common difference and 5th term of A.P

Find the sum of A.P first term 3 and common difference 2 and n=5

We are given an A.P. with 1st term a and common difference d. If each of the terms is multiplied by the same number c, is the resulting progression also an A.P. ? If so, find its common difference.

For A.P. : 6, 9, 12, 15, ……….. write the first term ‘a’ and common differene 'd' .

For the following A.P.s, write the first term and the common difference :- -5,-1,3,7,… .

For the following A.P.s, write the first term and the common difference :- 3,1,-1,-3…. .

We are given an A.P. with 1st term a and common difference d. If each of its terms is increased by the same quantity k, is the resulting progression also an A.P. ? If so, find its common difference.

If the sum of first 10 terms of an A.P. is 4 times the sum of its first 5 terms, then find the ratio of first term and common difference.
