Question
Find the seventh term of the expansion of (2x - 3)^10
Correct Answer
Option E is the correct answer.
Detailed Explanation
The (r+1)th term is C(n,r)(a)^(n-r)(b)^r. For the 7th term, r = 6: T7 = C(10,6)(2x)^4(-3)^6 = 210 × 16x^4 × 729 = 2449440x^4.
Hint
The 7th term corresponds to r = 6 in the binomial formula.
