Three Non-zero numbers a, b and c will be in G.P. If and only if ____.

Three numbers a,b and c are in the A.P if

In DeltaABC , show that the sides a, b, c are in A.P ., if and only if r_(1),r_(2),r_(3) are in H.P

Three non zero numbers a, b, c are in A.P. Increasing a by 1 or increasing c by 2, the number become in G.P then b equals

Write the condition under which three numbers a,b,c may be in A.P and G.P both.

in three positive numbers a, b and c are in A.P. such that abc = 8, then the minimum possible value of b is

Three numbers a, b and c are in between 2 and 18 such that 2, a, b are in A.P. and b, c, 18 are in G.P . If a+b+c=25 , then the value of c-a is

Three numbers a, b and c are in between 2 and 18 such that 2, a, b are in A.P. and b, c, 18 are in G.P . If a+b+c=25 , then the value of c-a is

Three non-zero numbers a ,b , c are in A.P. Increasing a by 1 or increasing c by 2, the numbers are in G.P. Then find b-a
