SOLUTION: What is the third term of the binomial expansion of {{{(x+2)^4}}}

The Rth term of the binomial expansion of  is



where  is the same as the combinations of
N things taken R-1 at a time, which is often written (N)C(R-1) and
often called "N choose R-1".

Therefore the third term of the expansion  is
found by substituting A=x, B=2, N=4, and R=3
