    32 and 39

    Step-by-step explanation:

    The common difference d for the sequence is 7

    1st term of the sequence a1 is 11.

    4th (a4) and 5th (a5) term of the sequence are required

    nth term of an arithmetic sequence an = a1 + (n-1) d

    a4=11 + (4-1) 7=32

    a5=11 + (5-1) 7=39
