Answer:
a) 49.41
b) not quite sure
Step-by-step explanation:
sorry
Answer:
B
$2.730 divided by 6 equals 455
$5,496 divided by 12 equals 458
458-455=3 so the answer is B
I would do 12 x 10 = 120
to compensate do 120 - 12 =108 same as 12*9 = 108
The estimate is decent, because we are only $12.00 from the real answer.
This is an arithmetic sequence, where the first term (a) is 15 and the common difference (d) is -2.
The general formula for the nth term of an arithmetic sequence is:

Therefore the required equation is:
