    25 because 45-5 = 40 and 40-5 = 35 and minus another five equals 30 and then minus another five equals 25

    25.

    Step-by-step explanation:

    This is called an Arithmetic sequence with common difference - 5.

    Adding - 5 to the 4th term (30) gives the fifth term (25).

    The explicit formula for the nth term:

    an = a1 + d (n - 1) where a1 = first term and d = the common difference.

    So here it is an = 45 + (-5) (n - 1)

    = 45 - 5n + 5

    = 50 - 5n.
