Answer 2

Answer:

91

Step-by-step explanation:

Given to find the next number of the series 1, 2, 6, 12, 25, 48, ?

Now there is a series called Fibonacci series. The sum of two preceding numbers is called Fibonacci series. The series goes like this 1, 1, 2, 3, 5, 8, 13, 21, 34 and so on.

Now let n be a set of natural numbers (1,2,3,4,5,6,7...........)

    So Z  = n x fib(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

hence the next number in the series is 91.
