Brian invest £4900 into his bank account he receives one. I.5% per year compound interest how much will Brian have after 4 years give your answer to the nearest penny where appropriate

A = $ 5,200.68

Step-by-step explanation:

A = P + I where

P (principal) = $ 4,900.00

I (interest) = $ 300.68

r = R/100

r = 1.5%/100

r = 0.015 per year,

Then, solve our equation for A

A = P(1 + r/n)nt

A = 4,900.00(1 + 0.015/1)(1)(4)

A = $ 5,200.68

The total amount accrued, principal plus interest,

from compound interest on an original principal of

$ 4,900.00 at a rate of 1.5% per year

compounded 1 times per year

over 4 years is $ 5,200.68.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
