We notice that the difference between the 2nd term & the first is equal to the difference of the 3rd with the second:

1-(-1) = (3-1) = 2 . So d (common difference ) =2

This is an arithmetic progression with first tem a₁ = (-1) & d =2

Calculating the nth term: Last term = a₁ + (n-1)d
10th term = (-1) + (10-1)(2)= -1 +(9x2) =17

3) You owe $1,842.66 on a credit card at a 14.5% APR. You pay $250.00 at the beginning of the month and put another $250.00 in a
Wittaler [7]

3. Credit Card: (1842.66 - 250) (.145/12) = $19.24

Difference = 19.24 - 0.83 = $18.41  

4. Credit Card: (1842.66 - 500) (.145/12) = $16.22

You will save $18.41 - $16.22 = $2.19 by putting all $500 toward the higher credit card rate.
