If 8 runners run in a race, how many permutations of runners can finish in 1st, 2nd, & 3rd place?

Did u want to find the value of x?

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
