(substitute into the arithmetic sequence equation (where an=285 and a1=5) and solve for n)
(just type in the answer)
Which is the nth term of the indicated sequence?
(1) find a1 using the term they give, a6.
(2) find a12 once you find a1.
(just type in the answer..as a fraction, if necessary)
Find the missing geometric means in each sequence (the missing terms)
(use a1=2 and a4=54 and n=4...find the r and then the missing terms)
