Find the values of t_1 and are for a geometric sequence with t_6= 4 and t_10 = 324.

==============================================

Work Shown:

Start with and multiply by the common ratio r to get the next term . Keep this going until you get to the 10th term

So we have...

From that we can see,

At this point, the only possible answer is choice C since this is the only answer choice with r = 3 in it. We could stop here if we wanted.

For the sake of completeness, let's find

You can use in place of in the section above, so either value is optional.
