The general term of the binomial expansion (a + x)^n is:
Correct answer: A. (n c r) a^(n-r) x^r
- A. (n c r) a^(n-r) x^r
- B. (n c r) a^(n-r) x^(n-r)
- C. (n c r) a^(r) x^(n-r)
- D. (n c r) (a x)^(n-r)
Explanation
The general term of the binomial expansion (a + x)^n is given by the formula:(n c r) a^(n-r) x^rWhere:n is the exponent of the binomial expressionr is the index of the term in the expansion(n c r) represents the binomial coefficient, which is the number of ways to c r objects from n objects.

About Sequences and Series
Sequences describe ordered terms formed by a pattern, while series represent the sum of those terms. Questions cover arithmetic and geometric sequences, their nth terms, common difference or ratio, finite sums, and applications, with the sequence itself kept distinct from the corresponding series.
