To find:

The missing term

Solution:

The required term is 400.

We can obtain the required term by multiplying the terms at means and the terms at extremes.

Let the required term be X.

The proportion becomes-

64:100:256:X

On multiplying, we get

64×X=100×256

X=25600/64

X=3200/8

X=400

So, the proportion is 64:100:256:400.

Therefore, the required term is 400.
