Find the missing number in the series?
87431 ---> 815 ---> 23 ---> ?
Ans: The number is 5. In this series group the odd and even numbers separately and add them you’ll get the next series of numbers. Similarly perform this till the last number of the series..
ie... 87431=>84+731=815
815=>8+15=23
23=>2+3=5
