1) Number Series
1) Which number should come next in the series, 48, 24, 12, ......?
It is a simple division series in which each number is one-half of the previous number. We can also say that each number is divided by 2 to arrive at the next number;
On dividing 48 by 2, we get 24
On dividing 24 by 2, we get 12
So, on dividing 12 by 2, we will get 6 (option B).
