Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

table payment and amount owed

Step 02:

arithmetic sequence:

an = a1 + d (n - 1)

a1 = 21700

a2 = 21425

d = a2 - a1 = 21425 - 21700 = - 275

an = a1 + d (n - 1)

an = 21700 - 275 (n - 1)

n = (7 + 1) = 8:

a (8) = 21700 - 275 (8 - 1) = 21700 - 275 (7) = 21700 - 1925 = 19775

The answer is:

after making his 7th payment he still owe 19775
