    Answer:

    -663

    Step-by-step explanation:

    The nth term of an arithmetic sequence is:

    aₙ = a₁ + d (n − 1)

    The first term is -14, and the common difference is -11.  So the nth term is:

    aₙ = -14 + (-11) (n − 1)

    So the 60th term is:

    a₆₀ = -14 + (-11) (60 − 1)

    a₆₀ = -663
