What is the rule for this function?

input 1 output 3
input 2 output 5
Input 4 output 9
Input 5 output 11
Input 10 output 21
Input 12 output 25

Please help now thanks

It is like adding

+9 then-7

y (output)

x(input)

y=2x+1

To determine the rule for this function, we need to look for a pattern or relationship between the inputs and outputs. Let's examine the given inputs and outputs:

Input 1, Output 3
Input 2, Output 5
Input 4, Output 9
Input 5, Output 11
Input 10, Output 21
Input 12, Output 25

By observing the inputs and outputs, we can notice the following pattern:
1. The output is always 2 more than the input.
2. However, when the input is a multiple of 4, the output is 4 more than the input.

Based on this pattern, we can conclude that the rule for this function is as follows:
- If the input is a multiple of 4, the output is the input value plus 4.
- For all other inputs, the output is the input value plus 2.
