In a sequence given by Tn = a + b bn the 6th and 13th terms are 22 and 71 respectively. Find the values of a and b.

Need some clarifications:

What is Tn?

Is it the nth. term? Then it should have been written as T(n).

Or is it T (multiplied by) n? Then it should have been written as T * n.

Or something else?

Then

what is b bn (I cannot even venture a guess). Also:

What are your thoughts?
