Find a formula for an for the arithmetic sequence. a3=94, a6=85

OpenStudy (anonymous):

Not sure on this one because it doesn't involve a1.

OpenStudy (anonymous):

Can you try to setup the equations?

OpenStudy (anonymous):

94= a1 + (3-1)d? Is that right for the first one? I don't see how I could solve it.

OpenStudy (anonymous):

That looks perfect to me yes.

OpenStudy (anonymous):

Am I solving the two together as a system of equations?

OpenStudy (anonymous):

that's right

OpenStudy (anonymous):

Awesome. Thanks so much again.
