FAQs on Sequence & Series Video Lecture - Reasoning and Military Aptitude Test for AFCAT

1. What is a sequence?

Ans. A sequence is a list of numbers arranged in a specific order. It can be finite or infinite and can follow a pattern or rule.

2. What is the difference between an arithmetic sequence and a geometric sequence?

Ans. In an arithmetic sequence, each term is obtained by adding a constant difference to the previous term. In a geometric sequence, each term is obtained by multiplying the previous term by a constant ratio.

3. How do you find the nth term of an arithmetic sequence?

Ans. To find the nth term of an arithmetic sequence, you can use the formula: nth term = first term + (n-1) * common difference. Here, the first term refers to the initial term of the sequence, n represents the position of the term in the sequence, and the common difference is the constant value added to each term.

4. What is the sum of an arithmetic series?

Ans. The sum of an arithmetic series can be calculated using the formula: sum = (n/2) * (first term + last term), where n is the number of terms in the series, and the first and last terms are the initial and final terms of the series, respectively.

5. How do you find the sum of a geometric series?

Ans. The sum of a geometric series can be found using the formula: sum = (first term * (1 - ratio^n)) / (1 - ratio), where the first term is the initial term of the series, ratio is the common ratio between consecutive terms, and n is the number of terms in the series.
