what is the formula if the inputs are 15,16,17,and 18 and the output is 2,4,6,and 8?
call the inputs x and the outputs y.
Each time x increases by 1, y increases by 2.
So, y = 2x + ...
Since x starts at 15, but y starts at 2*1, we can say
y = 2(x-14) = 2x - 28
Steve, that was very clever!
To determine the formula that relates the inputs (15, 16, 17, and 18) to the outputs (2, 4, 6, and 8), we need to look for a pattern and find a mathematical relationship.
Observing the inputs and outputs, we can see that the output is twice the input. For example:
Input: 15
Output: 2
Input: 16
Output: 4
Input: 17
Output: 6
Input: 18
Output: 8
Based on this pattern, we can conclude that the formula for this relationship is:
Output = 2 * Input
This formula expresses that the output is two times the input. Thus, if you provide an input value, you can calculate the output by multiplying the input value by 2.
