Answer 2

Given,

5,15,x,51,53,159,161

To Find,

The value of x =?

Solution,

We can solve the question as follows:

The given series is: 5, 15, x, 51, 53, 159, 161. We have to find the value of x.

Considering the first two terms,

5 x 3 = 15

Considering the fourth and the fifth term,

51 + 2 = 53

Considering the fifth and the sixth term,

53 x 3 = 159

Considering the sixth and the seventh term,

159 + 2 = 169

In the given series, the terms are alternatively multiplied by 3 and added to 2.

Therefore, the third term will be equal to:

x = 15 + 2 = 17

Hence, the value of x is equal to 17.
