If the sum of `4` terms of an `AP` is `36,` then `AM` of the `AP` is:

If the sum of 4 terms of an AP is 72 then find the AM of the AP

If the sum of 4 terms of an A.P. is 36, then find the A.M of the A.P.

If the sum of first 75 terms of an AP is 2625, then the 38th term of the AP is

If the sum of first 75 terms of an AP is 2625, then the 38th term of an AP is

In an A.P,the sum of m terms of an AP is n and sum of n terms of AP is m,then prove that sum of (m+n) terms of AP is-(m+n)

If the sum of the first four terms of an AP is 40 and the sum of the first fourteen terms of an AP is 280. Find the sum of first n terms of the A.P.

In an A.P.the sum of m terms of an AP is n and sum of n terms of AP is m,then prove that sum of (m+n) terms of AP is -(m+n)

If the sum of m terms of an A.P, is equal to the sum of n terms of the A.P ., then the sum of (m + n) terms is

If the sum of 12th and 22nd terms of an AP is 100 then the sum of the first 33 terms of an AP is

If the sum of 12 th and 22nd terms of an AP is 100 then the sum of the first 33 terms of the AP is
