[johnybarr]

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

[msh]

for the last question could you not sub in your a and r vaues inot the sum equation and work it out like that?

[sonderman]
