Question

Refer to the following number, symbol series and answer the question. Counting to be done from left to right only. (Left) # 5 4 @ % & * $ 6 8 Ω 9 1 7 3 £ + 2 (Right) How many such numbers are there each of which is immediately preceded by another number and also immediately followed by another number?

• A. 2
• B. 1
• C. 3
• D. 4

Answer 1

Answer:

A. 2

To find numbers that are both immediately preceded and immediately followed by another number, we are looking for a sequence of three consecutive numbers (Number - Number - Number).

Let's look at the given series from left to right:
# 5 4 @ % & * $ 6 8 Ω 9 1 7 3 £ + 2

Now, let's scan for any blocks of three numbers in a row:

• 5 4 (only two numbers, followed by @)

• 6 8 (only two numbers, followed by Ω)

• 9 1 7 3 (four consecutive numbers)

Let's break down the block 9 1 7 3:

• The number 1 is preceded by 9 and followed by 7. (Valid)

• The number 7 is preceded by 1 and followed by 3. (Valid)

There are 2 such numbers (1 and 7) in the series that meet the criteria.
