Show Answer

Correct Answer :

Option B

1.25

Solution :

The correct option is 1.25.

To find the missing number in the given series, let us analyze the pattern or relationship between consecutive terms:

4800÷2=2400

2400÷4=600

600÷6=100

100÷8=12.5

Observing the pattern, each term is obtained by dividing the previous term by consecutive even numbers (2, 4, 6, 8, ...).
Therefore, to find the next term (?), we need to divide 12.5 by 10:

?=12.5÷10=1.25

Thus, the missing number in the series is 1.25.
