7 Terms

11th term 2187

First Convert the Annual interest and Annual pay time to months
Time - r: 7 × 12 = 84
Interest per month - n: 0.00225

Use the Loan Amortization Formula
Then solve for the monthly payment amount M

First Year: $476.72
Total Pay: $3167.86

1.) First one CD: 5
2.) Last one CD: ½

3.) 1/64

Use Infinite series function
Solve for R algebra substitution

1) Explain it in plain words
2) Use the finite sequence formula
-First term a = 4*(0.8)
-Common ratio = (0.8)
-Don’t forget to add 2 meters
To find the total distance travelled in terms of n
3) Use infinite series

1i) r = (an)/(an-1)
Thus r = 4/(k-4) and r = (k+2)/4
(k+2)/4 = 4/(k-4)
ii) Cross multiply and solve for k
4 × 4 =(k-4)(k+2)
Simplify and rearrange to get
k^2−2k−24=0

2i)Use quadratic formula to solve for k
k = 6 k = -4
ii) Find all possible values of r

Substitute k into the r = equations from before

r = -0.5 and r = 2

Finite Series Formula Sn = (a1(1-r^n))/(1-r)
Infinite Series Formula Sn = a1/(1-r)
-1 < r < 1
