Question from mitch, a student: find an expression for T(n), the nth term of the sequence |
Mitch,
Try breaking it into two separate sequences:
Numerators: 1, 3, 5, 7, 9, ...
What is the expression for N(n)?
Denominators: 5, 8, 13, 20, 29,...
What is the expression for D(n)?
If you can come up with these two easier expressions, then
T(n) = N(n)/D(n) and you can just simplify from there.
Cheers,
Stephen La Rocque.
