    If we will analyze, we will notice a standard:

    From 54 to 50 we subtracted 4 - -> (-4); From 50 to 46 we subtracted 4 - -> (-4);

    This is repeated until last term of sequence.

    Terefore, the correct alternative is letter d).

    -4

    Step-by-step explanation:

    Take the second term and subtract the first term

    50 - 54 = - 4

    We can check by taking the third term and subtracting the second term

    46-50 = - 4

    The common difference is - 4
