Karolina [17]

Answer:

The new balance will be $385.04.

Monthly rate = 1.25%

Finance charge = 0.0125\times264.32 = $3.30

New purchases = $117.42

New balance = 264.32+3.30+117.42 = $385.04

Write an equation to represent the N'th term of the sequence (2,-1.-4,-7,...)
mr_godi [17]

Answer: a(n) = 5 - 3n

the sequence has:

a1 = 2

a2 = -1

a3 = -7

.........

we can see that: a2 - a1 = a3 - a2 = -3

=> the sequence is a  arithmetic sequence

=> the distance between the numbers is d = -3

because this sequence is a  arithmetic sequence

=> a(n) = a1 + (n - 1)d = 2 + (n - 1).(-3) = 5 - 3n
