Answer:
The missing term is 16
Step-by-step explanation:
The given series is 5, 4, 15, 7, 23, 11, 29, ? ,33
This series can be divided into two series :
( 5, 15, 23, 29, 33 ) and
( 4, 7, 11, ? )
In the first series, the next number is obtained by adding even numbers in decreasing order from 10,
5 + 10 = 15
15 + 8 = 23
23 + 6 = 29
29 + 4 = 33
In the second series, the next number is obtained by adding consecutive numbers starting from 3 ,
4 + 3 = 7
7 + 4 = 11
So the next term would be,
11 + 5 = 16
Hence,
The series would be 5, 4, 15, 7, 23, 11, 29, 16 ,33
