Look the series of numbers and find the missing number.

What Comes Next in the Sequence:

2 ; 8 ; 11 ; 18 ; 30 ; 47 ; 78 ; ?

Answer:

This is an alternate series of the following form;

2 + 8 + 1 = 11;

8 + 11 – 1 = 18;

11 + 18 + 1 = 30;

18 + 30 – 1 = 47;

30 + 47 + 1 = 78;

Therefore we can find the next number as;

47 + 78 – 1 = 124

Answer = 124
