# Which is the third term of the expansion (a + b)^{n}?

We will use the concept of binomial expansion in order to find the third term.

## Answer: The third term in the expansion of (a + b)^{n} = ^{n}C_{2} a^{2} y^{(n-2)} .

Let us see how we will use the concept of binomial expansion in order to find the third term.

**Explanation**:

Now according to the binomial expansion for the expression (x, y)^{n}, the formula for t_{th} term is equal to ^{n}C_{r} (x)^{r} (y)^{n-r}, where r = t - 1.
