The exponents of a start with n, the power of the binomial, and decrease to 0. This is the tricky variable to figure out. To find the fourth term of (2x+1)7, you need to identify the variables in the problem:
\na: First term in the binomial, a = 2x.
\nb: Second term in the binomial, b = 1.
\nn: Power of the binomial, n = 7.
\nr: Number of the term, but r starts counting at 0. And there's a couple of Direct link to Chris Bishop's post Wow. If there is a new way, why is that? An exponent says how many times to use something in a multiplication. This is the number of combinations of n items taken k at a time. It is commonly called "n choose k" because it is how many ways to choose k elements from a set of n. The "!" power is Y to the sixth power. Using the above formula, x = x and y = 4. be a little bit confusing. xn. figure it out on your own.

Direct link to loumast17's post sounds like we want to us, Posted 3 years ago. It normally comes in core mathematics module 2 at AS Level. Think of this as one less than the number of the term you want to find. Build your own widget . Since you want the fourth term, r = 3. Next, assigning a value to a and b. If the probability of success on an individual trial is p , then the binomial probability is n C x p x ( 1 p) n x .

\n \nEnter n in the first blank and r in the second blank.
\nAlternatively, you could enter n first and then insert the template.
\nPress [ENTER] to evaluate the combination.
\nUse your calculator to evaluate the other numbers in the formula, then multiply them all together to get the value of the coefficient of the fourth term.
