Answer 2

The misssing number of the given series (?) = 24

Step-by-step explanation:

The given series:

18, 24, 21, 27, ?, 30, 27

To find, the misssing number of the given series (?) = ?

The given series has two sequences.

First series(Odd places):

18, 21, ?, 27

The pattern follow:

+ 3, + 3, +3, .....

21 = 18 + 3 = 21

? = 21 + 3 = 24

27 = 24 + 3 = 27

Second series(Even places):

24, 27, 30

The pattern follow:

+ 3, + 3, +3, .....

27 = 24 + 3 = 27

30 = 27 + 3 = 30

The misssing number of the given series (?) = 24
