Find the middle term in the expansion of (2/x + x/2)^14


Expert Answer

Step 1

The middle term in the binmial  expansion of (x+a)^n is (( n/2)+1)th term, if n is even . If nis odd, then tere are two middle terms(n+1)/2 th and (n+3)/2 th terms

.Here, n=14, which is even, so, there is only one middle term , that is (14/2)+1=8th term

The formula for calculating the general term of the binomial expansion is shown on board.

Step 2

By substituting the values of x, a, n an...
