Step-by-step explanation:

find missing term series

18,8,27,16,45,24,?,32,108

Answer 2

Given:

A series of numbers 18,8,27,16,45,24,?,32,108

To Find:

The missing term in the series is?

Solution:

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

1. The given series is 18,8,27,16,45,24,?,32,108

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

=> Third term = first term + 9 = 18 + 9 = 27.

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

=> Fourth term = second term + 8  = 8 + 8 = 16,

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

=> Fifth term = third term + 9 + 9 = 27 + 18 = 45,

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

=> sixth term = fourth term + 8 = 13.12,

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

=> Seventh term = Missing term = Fifth term + 9 + 9 + 9 = 45 + 27 = 72,

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

=> Eighth term =  Sixth term + 8 =  24 + 8 = 32,

8. The ninth term of the series is obtained as,

=> Ninth term = Seventh term + 9 + 9 + 9 + 9  = 72 + 36 = 108.

Therefore, the missing term in the series is 72.
