    i'm not sure how to do this question??
    How many terms are there from the first to 4th term?
    What is the difference between 32 and 14?
    Then divide the difference between 32 and 14 by the number of terms between the 1st and 4th.
    Check your answer after by using a + (n-1)d.
    Hope this helps

    u_1=14
    u_2=14+d
    u_3=14+2d
    u_4=14+3d=32

    is the most basic way of doing it. Otherwise, use the formula.
