Thank you!

nnesha · Answer

n= number of the term we have to find 
so to find 9th term substitute n for 9 then solve

triciaal · Answer

let n = 9   I got 2

nnesha · Answer

anywys :/$$a_9=-14+(\color{ReD}{9}-1)(2)$$
remember PEMDAS rule 
parentheses first 
so first subtract (9-1) and then multiply by 2

Thanks for the help! Maybe I'll be able to get these sequence questions without help for once :P

np 
this topic isn't that hard just practice :=))
 all u need to do is remember geometric and sequence formulas that's it ! :=))
good luck!
