The middle term of the expansion (1 + 2x)⁶ is?
- 2nd term
- 3rd term
- 4th term
- None of these
Explanation
Binomial ExpansionGiven: (1 + 2x)^6
The number of terms in the expansion is n + 1 = 6 + 1 = 7, which is odd.
The middle term is the n + 1/2 + 1 - 1 = 7/2 = 3.5, so the 4th term is the middle term.
