Question

Complete the given series by finding the missing term.

11 13 17 25 32 ___ 47

Answer 1

This is a tricky problem If we analyse the first four terms it appears as if the difference between two consecutive terms keeps on doubling in each stage However this pattern does not hold between the two consecutive terms 25 and 32 Hence we should think of some different pattern
Take any term Find the sum of digits of the term and add it to the same term We get the next term This pattern continues throughout the series By applying this pattern we can find the missing term as 37.
