Question

Refer to the following number series and answer the question.

2 5 6 9 8 0 3 8 6 7 2 5 2 2 6 8 3 6 5 3

How many such numbers are there in the series each of which is immediately preceded by an even number and immediately followed by an odd number?

• A. 2
• B. 5
• C. 3
• D. 4

Answer 1

Answer:

D. 4

There are 4 numbers in the series that are immediately preceded by an even number and immediately followed by an odd number.

We need to find groups that fit the pattern: Even Number $\rightarrow$ Target Number $\rightarrow$ Odd Number
(Even numbers include 0, 2, 4, 6, 8. Odd numbers include 1, 3, 5, 7, 9.)

Let's check the sequence carefully from left to right:

1. 8 0 3 $\rightarrow$ The number 0 is preceded by even 8 and followed by odd 3.

2. 8 6 7 $\rightarrow$ The number 6 is preceded by even 8 and followed by odd 7.

3. 6 8 3 $\rightarrow$ The number 8 is preceded by even 6 and followed by odd 3.

4. 6 5 3 $\rightarrow$ The number 5 is preceded by even 6 and followed by odd 3.
