Answer 2

Given:

7,21,63,189,567,?

To find:

The last term

Solution:

The required term is 1701.

We can obtain the required value by forming a pattern between the given terms.

Let the last term be x.

The following are the given terms-

7, 21, 63, 189, 567, x

Now, we see that each successive term is thrice of the previous term.

The first term=7

The second term=7×3=21

The third term=21×3=63

The fourth term=63×3=189

The fifth term=189×3=567

The last term=x=567×3

x=1701

Therefore, the required term is 1701.
