AM of 2 terms

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.

The AM and GM of two terms a and b are 20 and 16 the terms a' and 'b' are

ABCD is a parallelogram.If L and M are the mid-points of BC and DC respectively,then express vec AL and vec AM in terms of vec AB and vec AD Also,prove that vec AL+vec AM=(3)/(2)vec AC .

If AM of numbers x_(1),x_(2)…..x_(n) is mu , then what is tha AM of the numbers which are increased by 1, 2, 3, …..n respectively?

If the A.M of roots of quadratic is (delta)/(5) and AM of their reciprocal is (8)/(7) then the quadratic equation is B find the minimum value of x^(2)+2xy+3y^(2)-6x-2y

A.M || G.P(nth term & sum OF n terms)

If the sum of four numbers in G.P. is 60 and the A.M. of he first and the last is 18 then the four terms of the G.P. are
