What is the coefficient of the third term in the binomial expansion of (a + b)6?

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?

5i the answer

25, 14 1/2 , 6.3, 1.15, -1/4, -3 and -5.6
