Question

For the given A.P write the first term termand the common difference:-
(a) 34,32,30,........ a=______; d=_____.
(b) -5, -1, 3,7,......... a=______; d=_____.​

Answer 1

First term = a = 3

common difference = d = difference between two consecutive terms

                                       = Second term -First term

                                       = 1-3

                                       = -2

                                       Hence, a= 3 and d= -2
