for exam style question 3 what is the point in splitting it when you can just input the information straight into the geometric Sn formula using the starting point as a=3/32 r=1/2 and n=100

[@sabrinakahie7891]

yeh was just gonna comment this

[@pratheesh2105]

if you mean n=95, yeah that works too you get the same value

[@adnaanahmed6161]

N needs to equal 96

[@aeshakhan-by2bu]

n would be 96

[@Karim-lj5fp]

A level paper 1 today, goodluck everyone

[@_trm_4339]

imagine tlmaths and zeeshan collaborated

[@aeshakhan-by2bu]

13:50 couldn't you just sub in 5 for the value of r and use that as a to find the sum?

[@HaqqIsTheWay155]

Nah then you can't work out a cause it starts from the 5th term

[@hayleycrowhurst3998]

@@HaqqIsTheWay155 you still get the same answer
