What is the next number in the series?5  11  23  47

The next number in the series is 95.

Here's the step-by-step explanation:

1. Look at the series and try to identify a pattern. The series is: 5, 11, 23, 47.

2. Notice that each number is approximately double the previous number.

3. To find the exact pattern, see how much you need to add to each number to get the next one: 11-5=6, 23-11=12, 47-23=24.

4. Notice that these differences (6, 12, 24) are doubling each time.

5. So, to find the next number, double the last difference (24) and add it to the last number in the series (47).

6. 24*2=48, and 47+48=95.

So, the next number in the series is 95.
