Answer:

$\star}answer}}}$

3, 1, - 1, - 3 …

Here, first term, a = 3

Common difference, d = Second term - First term

= 1 - 3 = - 2

(ii) - 5, - 1, 3, 7 …

Here, first term, a = - 5

Common difference, d = Second term - First term

= ( - 1) - ( - 5) = - 1 + 5 = 4

(iii) 1/3, 5/3, 9/3, 13/3 ....

Here, first term, a = 1/3

Common difference, d = Second term - First term

= 5/3 - 1/3 = 4/3

(iv) 0.6, 1.7, 2.8, 3.9 …

Here, first term, a = 0.6

Common difference, d = Second term - First term

= 1.7 - 0.6

= 1.1
