340.Write first four terms the A .P. when the first term ‘a’ and the common difference ‘d’ are given as follows :
a = 4, d = – 3
a = 4, d = –3 First term = a = 4 Second term = 4 + d = 4 + (–3) = 1 Third term = 1 + d = 1 + (–3) = –2 Fourth term = –2 + d = –2 + (–3) = –5 Hence, four first terms of the given A .P. are 4, 1, -2, -5.
