A basic and conceptual question from arithmetic progression chapter in which we have given a series of AP 3, 7, 11, 15 and we have to find whether 184 is a term of the above series?

Book RS AGGARWAL, arithmetic progression, chapter 5A, question 22

  1. Here 1st term (a) = 3 and common difference (d) = 7 – 3 = 4
    nth term an=a+(n1)d
    184=3+(n1)4
    181=4n4
    185=4n
    n=4185
    Since n is not a natural number
     184 is not a term of the given sequence
