The middle term of (a + b)⁶ is the:
The expansion of (1 + x)³ is:
The general term in (a + b)^n is:
The coefficient of x³ in (1 + x)⁴ is:
1. C, 2. D, 3. C, 4. C, 5. A, 6. A, 7. D, 8. A
There are n + 1 terms.
5C2 = 10.
Put x = 1: 2⁴ = 16.
It proves a statement for every natural number.
There are 7 terms, so the middle one is the 4th.
The binomial coefficients are 1, 3, 3, 1.
This is the (r + 1)th term.
4C3 = 4.
