# Arithmetic Progressions

#### Answer:

Here, we are given the *n*^{th }term for various sequences. We need to find the first five terms of the sequence.

(i)

Here, the *n*^{th} term is given by the above expression. So, to find the first term we use, we get,

Similarly, we find the other four terms,

Second term (),

Third term,

Fourth term,

Fifth term,

Therefore, the first five terms for the given sequence are.

(ii)

Here, the *n*^{th} term is given by the above expression. So, to find the first term we use, , we get,

Similarly, we find the other four terms,

Second term (),

Third term,

Fourth term,

Fifth term,

Therefore, the first five terms for the given sequence are.

(iii)

Here, the *n*^{th} term is given by the above expression. So, to find the first term we use, we get,
