1.	The algebraic forms of some sequence are given below. Check whether each of them is an arithmetic sequence or not; also find out the first term and the common difference of the arithmetic sequence(i) xn = 4 − 3n(ii) xn = n2 + 2(iii) (iv) (v) xn = (n + 1)2 − (n − 1)2
Answer» The algebraic forms of some sequence are given below. Check whether each of them is an arithmetic sequence or not; also find out the first term and the common difference of the arithmetic sequence (i) x_n = 4 − 3n (ii) x_n = n² + 2 (iii) (iv) (v) x_n = (n + 1)² − (n − 1)²

Answer»

The algebraic forms of some sequence are given below. Check whether each of them is an arithmetic sequence or not; also find out the first term and the common difference of the arithmetic sequence

(i) x_n = 4 − 3n

(ii) x_n = n² + 2

(iii)
