In the A.P. `3,5,7,…43`, find the middle term :

The first and last terms of an A.P. are - 7 and 233 and the sum of the A.P. is 9153. Find the number of terms in the A.P.:

Suppose that the first and the 5^(th) terms of an A.P. are-14 and 2 respectively If the sum of the terms of the A.P is 40, find the number of terms in the A.P.

The 17th term of an A.P. is 5 more than twice its 8th term. If the 11th term of the A.P. is 43, find the n^(t h) term.

In a sequence of 21 terms, the first 11 terms are in A.P. with common difference 2 and the last 11 terms are in G.P. with common ratio 2. If the middle term of the A.P. is equal to the middle term of the G.P., then the middle term of the entire sequence is

In a sequence of 21 terms the first 11 terms are in A.P. with common difference 2. and the last 11 terms are in G.P. with common ratio 2. If the middle tem of the A.P. is equal to the middle term of the G.P., then the middle term of the entire sequence is

In a sequence of 21 terms the first 11 terms are in A.P. with common difference 2. and the last 11 terms are in G.P. with common ratio 2. If the middle tem of the A.P. is equal to the middle term of the G.P., then the middle term of the entire sequence is

In a sequence of 21 terms the first 11 terms are in A.P. with common difference 2. and the last 11 terms are in G.P. with common ratio 2. If the middle tem of the A.P. is equal to the middle term of the G.P., then the middle term of the entire sequence is

If the nth term of the A.P. 9,7,5,... is same as the nth term of the A.P. 15,12,9,.. find ndot

Find the value of the middle most term of AP: -11,-7,-3,...,49

The sum of three numbers in G.P. is 70. If the first and last term are multiplied by 4 and the middle term by 5, then they will be in A.P., find them.
