    Answer:

    a = 4

    d =5

    a(n) = 249

    n=?

    a(n) = a+ (n-1)d

    249 = 4+( n-1)5

    245 = 5×(n-1)

    n-1 = 49

    n = 50

    which is the required ans

    Answer:

    the term is 50th

    Step-by-step explanation:

    nth term = a + (n-1)d

    249 = 4 + (n-1)5

    (249-4)/5= n-1

    245/5 = n-1

    49 = n-1

    n = 50
