For the geometric I got a = 1000 as s=a/1-r so 1-r = 0.1?

a = 19,000

What was question 7

For people saying a was 1000, it had to be 19000 as if you do the sum equation, n tends towards infinity at large values (ie 500), sum to infinity was 10k and you only get this value with 19000 and with 1000 you get 567

Isn’t question 7 625.56 for the value of y?

How do you do 7a) ?

You’ll get one mark but not both as it said simplified I’m pretty sure
