Question

FIND THE NEXT NUMBER IN GIVEN SERIES 1,2,6,12,25,48,?

Answer 1

Next number in the series is 91.

Because:

1, 2, 6, 12, 25, 48

The Fibonacci sequence (0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...) is a series where the next term is the sum of previous two terms. The first two terms of the Fibonacci sequence is 0 followed by 1.

Sequence of natural numbers (1,2,3,4,5,6,7...........)

= n x fib(n)= Natural numbers x Fibonacci number(n)  

              = 1 x 1 = 1

            =   2 x 1 = 2

             =   3 x 2 = 6

             =   4 x 3 = 12

            =    5 x 5 = 25

             =   6 x 8 = 48

            =    7 x 13 = 91

              So on …
