In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.

b _ b _ bb _ _ bbb _ bb _ b

The series is babb / bbab / bbba / bbbb. Thus, in each sequence, a moves one step forward and b takes its place and finally in the fourth sequence, it is eliminated..

Look at this series: 3, 4, 7, 8, 11, 12, . . .

What number should come next ?

What number should come next ?

This alternating addition series begins with 3;

then 1 is added to give 4;

then 3 is added to give 7;

then 1 is added, and so on.

Rule = (first number + 1), (second number + 3), (third number + 1), (fourth number + 3)...

Now The series is 3, 4, 7, 8, 11, 12...

(3 + 1 = 4), (4 + 3 = 7), (7 + 1 = 8), (8 + 3 = 11), (11 + 1 = 12), (12 + 3 = 15)...

So the answer is 15..
