In an arithmetic sequence {an}, if a1 = 5 and d = 3, the first 4 terms in the sequence are a) {9, 6, 3, 0, }. b) {5, 8, 11, 14, }. c) {5, 2, -1, -4, }. d) {5, 15, 45, 135, }.

A1 represents the first term

d represents the common differenceand since the common difference is 3, u have to add 3 to each term to find the next termbecause with an arithmetic sequence u add to find the next term, whereas, in a geometric sequence u multiply to find the next term

5...first term
5 + 3 = 8...2nd term
8 + 3 = 11...3rd term
11 + 3 = 14...4th term

ur answer is B
