    An=a1+d (n-1)

    a1=first term

    d=common differnce

    easy

    inptu 4 for n and 10

    a4=5 + (4-1) 1/2

    a4=5+3 (1/2)

    a4=5+3/2

    a4=6 and 1/2

    4th term is 6 and 1/2

    10th term

    a10=5 + (10-1) 1/2

    a10=5 + (9) 1/2

    a10=5+9/2

    a10=9 and 1/2

    4th term is 6 and 1/2
