fi'd the next fifth number from the given set 17,90,48,and 84

To find the next fifth number in the given set, we need to first determine the pattern or rule underlying the set. Looking at the set of numbers: 17, 90, 48, 84, we can attempt to find a pattern.

One possible pattern is that each number in the set is obtained by multiplying the preceding number by a certain factor and adding a constant value.

Let's find the factors for each number pair:
- 90 divided by 17 is approximately 5.29
- 48 divided by 90 is approximately 0.53
- 84 divided by 48 is approximately 1.75

Since the factors are not consistent, it seems that multiplication is not the rule for determining the next number.

Another possible pattern is that each number is obtained by combining the digits of the previous number and adding a constant value.

Let's examine the digit combinations for each number:
- 17
- 90 = 9 + 0 = 9
- 48 = 4 + 8 = 12
- 84 = 8 + 4 = 12

In this pattern, each number is derived by adding the digits of the previous number.

Using this pattern, let's find the next number in the set:
- 12 + 12 = 24

Therefore, the next fifth number in the set 17, 90, 48, 84 is 24.
