    Answer:

    The answer is given below

    Step-by-step explanation:

    Given that,

    a = 15

    a_{12} = 124 ———–(1)

    Substituting a = 15 in equation (1)

    General formula for Arthematic Progression is

    a_{n} = a + (n-1)d

    a_{12} = a + (12-1)d

    124 = 15 + 11d

    124 – 15 = 11d

    109 = 11d

    d = \frac{109}{11}

    d = 109/11

    So,The value of d = 109/11
