Answer:
=
+ 3 ; a₁ = 1
Step-by-step explanation:
Given
1, 4, 7, 10, 13, 16, ......
Note the difference in consecutive terms is constant, that is
4 - 1 = 7 - 4 = 10 - 7 = 13 - 10 = 16 - 13 = 3
Thus to obtain the next term in the sequence ( recursive formula )
Add 3 to the previous term
=
+ 3 ( with a₁ = 1 )
So,
The standard form is:
y = mx + b
First, we find "m," the slope. Subtract the y-coordinates from each other. Do likewise with the x-coordinates.
2 - -3 = 5
2 - 0 = 2
Slope = 5/2

Now, we can substitute the second solution into this equation for x and y and solve for "b."


Now we have our complete equation.
33/4 is the same as 8 1/4
so that means that matt bought the Volvo for 8 1/4 times as much as the car his parents bought.
therefore... 8,000 times 8.25 = 66,000
