## FAQs on Shortcuts: Arithmetic Progressions Video Lecture - Quantitative Aptitude for SSC CGL

 1. What is an arithmetic progression?
Ans. An arithmetic progression is a sequence of numbers in which the difference between any two consecutive terms is always the same. This difference is called the common difference.
 2. How can I find the nth term of an arithmetic progression?
Ans. To find the nth term of an arithmetic progression, you can use the formula: nth term = first term + (n - 1) * common difference. Substitute the values of the first term, n, and the common difference into this formula to find the nth term.
 3. Can the common difference of an arithmetic progression be negative?
Ans. Yes, the common difference of an arithmetic progression can be negative. The common difference represents the amount by which each term increases or decreases from the previous term. It can be positive or negative depending on the pattern of the sequence.
 4. How can I determine the sum of the terms in an arithmetic progression?
Ans. The sum of the terms in an arithmetic progression can be found using the formula: sum = (n/2) * (first term + last term). Here, n represents the number of terms in the progression, and the first and last terms are the initial and final values of the sequence. Substitute these values into the formula to calculate the sum.
 5. Can an arithmetic progression have an infinite number of terms?
Ans. No, an arithmetic progression cannot have an infinite number of terms. Since the common difference between terms is constant, the progression will eventually reach a point where it becomes infinite. The number of terms in an arithmetic progression is always finite.
