Adam buys a car for £18680 which depreciates in value at a rate of 2.5% per year. Work out how much Adam's car will be worth in
timofeeve [1]

Answer:

Adam's car will be 8,406£ in 22 years.

Step-by-step explanation:

I. Find the lose value of 2.5% car by

2.5/100 = x/18,680

46,700/100 = x

x = 467 or the lose value in 1st year.

II. Find the true value of Adam's car by

n year = 18,680 - 467(n)

1st = 18,680 - 467(1)

    = 18,213 means if he sell his car now, he'll get 18,213£

22th = 18,680 - 467(22)

        = 18,680 - 10,274

        = 8,406£

That makes 8,406£ is the right answer.

Hope that help :)

PLEASE HELP!
FinnZ [79.3K]

Answer:

Terms are 2 , 3 , 7 , 31

Step-by-step explanation:

1) given a1 = 2

an+2 = 2(an) -1

put n = 1

a1 + 2 = 2a1 -1

put value of a1 in above

you'll get a3 = 2² -1

a3 = 4-1

a3 = 3

put n = 3

a3 + 2 = 2a3 -1

a5 = 2³-1

a5 = 8-1

a5 = 7

put n = 5

a5 + 2 = 2a5 -1

a7 = 2⁵ -1

a7 = 32 -1

a7 = 31

Hope you got it.

Similarly you can find 2nd one's term t23

tn = 5*n -4

here n = 23

t23 = 5 * 23 - 4

t23 = 115 -4

t23 = 111

Hope this helps you.
