    True

    Step-by-step explanation:

    For the sequence to be arithmetic the difference d between consecutive terms must be equal.

    - 11 - ( - 6) = - 11 + 6 = - 5

    - 16 - ( - 11) = - 16 + 11 = - 5

    - 21 - ( - 16) = - 21 + 16 = - 5

    - 26 - ( - 21) = - 26 + 21 = - 5

    Since there is a common difference between terms the sequence is arithmetic.
