Answer 2

Given:

A series of numbers 1, 4, 20, 23, 115, ----, 590​

To Find:

The missing number in the series is?

Solution:

The given problem can be solved by developing a common logic between every term.

1. The given series is 1, 4, 20, 23, 115, ----, 590​

2. The second term in the series is obtained as,

=> Second term = 4 = 1 + 3,

3. The third term of the series is obtained as,

=>Third term = 20 = 4 x 5,

4. The fourth term of the series is obtained as,

=>Fourth term = 23 = 20 + 3,

5. The fifth term of the series is obtained as,

=>Fifth term = 115 = 23 x 5,

6. The sixth term of the series can be obtained using similar logic,

=> Sixth term = 115 + 3 = 118.

7. The seventh term of the series is obtained as,

=>Seventh term = 590 = 118 x 5.

Therefore, the missing number in the series is 118.
