I just gave you the answer to number1.
If I give you the answers I shall be breaking the rules of Ask Me Help Desk.

First thing, T_n means the term n of a sequence. So, T_1 means that it is the first term of a sequence.

Now, an arithmetic progression is a sequence where the you have a fixed value added or removed from the previous term.

If you are given the equation of a sequence, for example, T_n =2n+1 replacing n by the term number will give you the term you're looking for.
