What is the n ^th term of each binomial expansion?

Finding Specific Terms in a Binomial Expansion Using the Binomial Theorem we can write a formula to find any term we want in an expansion without having to completely expand a binomial. To find the term in position r of (x + y)": ncrx- ry ** Be careful, the term number is not the same as its position number! The position number, r. is one less than the term number. Example 2. Find the specified nth term of each binomial expansion. A) (x - y)5, n = 1 B) (2m - 5) 4, n = 3 ( 20 ) C) (-x + 3y)5, n =4 D) (3x - y)8, n = 2
