would it be C @myininaya

myininaya · Answer

$$A(n)=1+(n-1)(-4.1) \ A(1)=1+(1-1)(-4.1)=1+0=1 \ A(2)=1+(2-1)(-4.1)=?$$

myininaya · Answer

I don't think that will output any of your choices

myininaya · Answer

are you sure you wrote your problem correctly?

myininaya · Answer

oh fourth term

myininaya · Answer

you can find the fourth term by replacing n with 4

myininaya · Answer

and then tenth term can be found by replacing n with 10

myininaya · Answer

so yeah that seems right
