Answer:
the yearly interest would be 160.00
Step-by-step explanation:
The explicit rule for any arithmetic sequence is:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number
In this case a=-3 and d=7 so:
a(n)=-3+7(n-1)
a(n)=-3+7n-7
a(n)=7n-10
The value of x is 13 for the first attachment.
-- Take. -5 . -- Add 12. to it. -- To the result, add 10. --- From that result, subtract 7 . -- The current result is the value of the expression.
