Answer:
The exponential model is
.
Step-by-step explanation:
The exponential model can be modelled by the following mathematical expression:
(1)
Where:
- Independent variable.
- Dependent variable.
- Coefficients.
If we know that
and
, then we get the following system of equations:
(2)
(3)
If we divide (3) by (2), we calculate the value of
:



And by (2), we determine the value of
:


The exponential model is
.
7 x 6 = 42 x 5 = 210 x 8 = 1,680 x 4 = [ 6,720 ]
12 because the rest of the numbers are all similar except 12
