Hi
The greatest coefficient is 4 th term option b
We know that the formula for greatest coefficient is
If we consider n = 8
Then there are n+1 terms.
Here there 9 terms as there are odd number of terms the term with greatest coefficient is n/2 th term.
here n/2 = 4
Hence 4th term's coefficient is greatest.
