    Given :

    • First term (a) = 10
    • Common difference (d) = 3

    To Find :

    • First four terms

    Solution :

    ⇒a1 = a

    ⇒a1 = 10

    ___________________

    ⇒a2 = a + d

    ⇒a2 = 10 + 3

    ⇒a2 = 13

    ___________________

    ⇒a3 = a + 2d

    ⇒a3 = 10 + 2(3)

    ⇒a3 = 10 + 6

    ⇒a3 = 16

    __________________

    ⇒a4 = a + 3d

    ⇒a4 = 10 + 3(3)

    ⇒a4 = 10 + 9

    ⇒a4 = 19

    _____________________

    \therefore A.P is 10,13,16,19....
