In the following question, select the missing number from the given series.
11, 16, 21, 13, 19, 25, 15, 22, 29, ?, 25
The given series is a combination of three alternate series which are shown below
11, 13, 15, ?
16, 19, 22, 25
21, 25, 29
From the first series,
11 + 2 = 13
13 + 2 = 15
Similarly, the next number = 15 + 2 = 17
$$\therefore\ $$The missing number of the given series is 17.
Hence, the correct answer is Option B
