Answer 2

Given:

A series of numbers 11,12,15,21,31,46,?

To Find:

The next 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 11,12,15,21,31,46,?.

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

=> Second term = 12 = 11 + 1,  

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

=>Third term = 15 = 12 + 1 + 2,  

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

=>Fourth term = 21 = 15 + 1 + 2 + 3,

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

=>Fifth term = 31 = 21 + 1 + 2 + 3 + 4,  

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

=>Sixth term = 46 = 31 + 1 + 2 + 3 + 4 + 5,

7. The seventh term of the series can be obtained using similar logic,

=> Seventh term = 46 + 1 + 2 + 3 + 4 + 5 + 6,

=> Seventh term = 46 + 21 = 67.

Therefore, the next number in the series is 67.
