Which of the following statements regarding the expansion of (x+y)^n is correct? A. For any term x^ay^b in the expansion, a+b=n
B. The coefficients of x^ay^b and x^by^a are equal
C. The coefficients of x^n-1 and y^n-1 both equal one
D. For any term x^ay^b in the expansion, a-b=n

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?
