Hello from MrBillDoesMath!

Answer:

a(n) = 12 - 3(n-1)          , n = 1,2,3.,,



Discussion:

The terms are 12, 9, 6, 3  so we are apparently subtracting 3 from each succeeding term. . Hence

a(n) = 12 - 3(n-1)          , n = 1,2,3.,,


Thank you,

MrB

NNADVOKAT [17]

Answer:

The answer is A) Round 56 to 60, find 10%, then double.

Step-by-step explanation:

You would round to 60 because 56 is closer to 60 than 50 then 10% is half of 20% so you would double it after you found 10% of 60.

Hope this helps :)
