FAQs on G.P NCERT Examples: Sequence and Series Video Lecture - Mathematics for GRE Paper II

1. What are the types of sequences and series covered in the NCERT examples on GP?
Ans. The NCERT examples on GP cover arithmetic, geometric, and harmonic sequences and series.
2. How can I identify if a sequence is arithmetic or geometric?
Ans. To identify if a sequence is arithmetic, check if the difference between consecutive terms is constant. If the ratio between consecutive terms is constant, then the sequence is geometric.
3. How do I find the sum of an arithmetic series using the NCERT examples on GP?
Ans. To find the sum of an arithmetic series, you can use the formula Sn = (n/2)(2a + (n-1)d), where Sn is the sum of the first n terms, a is the first term, and d is the common difference.
4. How can I find the common ratio in a geometric sequence using the NCERT examples on GP?
Ans. To find the common ratio in a geometric sequence, divide any term by its previous term. The result will be the common ratio.
5. Can the sum of an infinite geometric series be calculated using the NCERT examples on GP?
Ans. Yes, the sum of an infinite geometric series can be calculated using the formula S = a/(1 - r), where S is the sum, a is the first term, and r is the common ratio. However, this formula is applicable only when the absolute value of the common ratio is less than 1.
