c) 17
d) 20.25
e) other than the given option​

Answer 1

Answer:

HELLO THERE!!

Explanation:

The series is  

122/2+1=62

62/2+1 =32

32/2+1 =17

17/2+1  = 9.5

9.5/2+1 = 5.75

ANSWER] OPTION C) 17

Answer 2

Given:

122, 62, 32, ?, 9.5, 5.75

To find:

The missing term

Solution:

The required missing term is 17. (Option c)

Let the required term be X.

In the sequence, the difference between two consecutive terms becomes half as the terms reduce.

122-62=60

62-32=60/2=30

So, 32-X=30/2=15

32-X=15

32-15=X

X=17

Following the pattern further,

17-9.5=15/2=7.5

9.5-5.75=7.5/2=3.75

Thus, the required term that is missing is 17.
