    Answer:

    Step-by-step explanation:

    For n Arithmetic Means between two Numbers a & b the formula for xth Arithmetic Mean is:

    Aₓ= a+ x(b-a)/(n+1)

    Here; n=total means =4

    a= 1st number=10

    b=20, x= Number of mean

    A₁= 10+1(20-10)/(4+1) = 10+10/5 = 10+2 = 12

    A₂= 10+2(20-10)/(4+1) = 10+2(10)/5=10+4= 14

    Now you can see that common difference is going on d=2 you can easliy 2 further to get A₃ & A₄ which will be 16 and 18 respectively.
