If `a,b,c` are in AP and p is the AM between a and b and q is the AM between b and c, then show that b is the AM between p and q.

If a, b, c are in AP, x is the GM between a and b, y is the GM between b and c, then show that b^(2) is the AM between x^(2) and y^(2) .

Let a,b,c be in A.P. If p is the A.M. between a and b and q is the A.M between b and c, then b is equal to

If a is the A.M. between b and c, b the G.M. between a and c, then show that 1/a,1/c,1/b are in A.P.

If a is the A.M. between b and c, b the G.M. between a and c, then show that 1/a,1/c,1/b are in A.P.

If x is the A.M. between a and b, y is the A.M. between b and c, while a, b, c are in G.P., then 1/x + 1/y =

If the A.M between a and b is m times their H.M then a:b is

If the A.M between a and b is m times their H.M then a:b is

a , b , c , d are in increasing G.P. If the AM between a and b is 6 and the AM between c and d is 54 , then the AM of a and b is
