  Hi Shubhangi smile

You can easily check with some numbers that it is not compulsory for a, b, c to follow either AP or GP.

For example, let's take x = 1, y = 2 and z = 4 such that x, y, z are in AP.

Now let a = 16, b = 4 and c = 2 such that ax
= by = cz i.e. 161 = 42 = 24.

But you can easily see that 16, 4, 2 are neither in AP or GP.
