Work out the balance for £4500 invested for 2 years at 4% per annum

This situation can be represented by a geometric sequence, where each term is the balance each successive year:

Un = the balance on the nth year

a = intial balance

r = multiplier

n = number of years

From the information:

a = 4500

r = 1.04

(4% increase per annum is the equivalent of multiplying by 1.04 so the multiplier is 1.04)

n = 2

So:

The balanc after two years is: £4867.20

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
