Between 1 and 31, n A.M's have been inserted in sucha a way that the ratio of 7th and (m-1)th means is 5:9, find the value of m.

If m = 2, find the value of: 9 – 5m

If m = 2, find the value of: 3m – 5

Between 1 and 31, m numbers have been inserted in such a way that the resulting sequence is an A. P. and the ratio of 7th and (m -1)^(th) numbers is 5 : 9. Find the value of m.

n arithmetic means are inserted between 3 and 17 such that ratio of first and the last means is 1: 3, find n.

If m = 2, find the value of: 3m^2 – 2m – 7

Find the ratio of: 9m to 27 cm

There are n arithmetic means between 3 and 17. The ratio of the last mean to the first mean is 3: 1. Find the value of n.

There are n AM's between 3 and 54.Such that the 8th mean and (n-2) th mean is 3 ratio 5. Find n.

If the sum of n terms of an A.P. is 3n^2 + 5n and its m^(th) term is 164, find the value of m.
