amistre64 · Answer

i think your 'rule' is not presented correctly

cookiemonster18 · Answer

No it is. That's how it's shown on the worksheet 

A(n)=-14(n-1)(2)

amistre64 · Answer

its just that that does not resemble any sort of arithmetic sequence that I am familiar with ...

amistre64 · Answer

an arith seq is generated by some rule:

A(n) = A(n-1) + d

such that each new term is defined as the addition of d (the common difference) to the previous term.

amistre64 · Answer

IF its a closed expression

A(n) = A(1) + d(n-1)  is equivalent

amistre64 · Answer

if you are able to decipher your rule, then just let n=9 and work the math for the solution
