Answer 1

Given series:

5 $ 5 % 8 7 * 5 % & 8 @ 2 6 2 £ 3 8 1 & 5 6

Condition to be checked:

Number which is immediately preceded by a number and also immediately followed by a number.

Number → Number → Number

Let's go through the series and identify such patterns:

5 $ 5 % 8 7 * 5 % & 8 @ 2 6 2 £ 3 8 1 & 5 6

Thus, there are two such numbers ('6' and '8') that are immediately preceded by a number and also immediately followed by a number.

Hence, the correct answer is "Option 2".

Mistake Points

Immediately preceded by means immediately before or to come just before.

Immediately followed by means immediately after or to come just after.
