You can`t really do that.

Explanation:

I`m not sure what you want is possible unless you were given the formula for that sequence. Otherwise you'll have to figure out the relevant formula before you plug it into the calculator.

Example: If I tell you to give me the 10th number in the sequence:
#2,5,10,17,26,...# YOU have to figure out that the "formula" for that sequence is #f(n)=n^2+1# and then you can plug #10^2+1# in the calculator and find the answer. So unless you get the formula, the hard work (finding it) is up to you.
