Passage 1:
In mathematics, a number sequence is an ordered list of numbers that follow a specific pattern or rule. One common example is the arithmetic sequence, where the difference between each number is the same. For instance, in the sequence 2, 5, 8, 11 …, the difference between each number is 3. Another important type of sequence is the geometric sequence, where each term is found by multiplying the previous one by a fixed number called the common ratio. For example, in the sequence 3, 6, 12, 24, …, each number is multiplied by 2. The Fibonacci sequence is another famous number sequence where each number is the sum of the two before it, starting from 0 and 1. These sequences are found in real life, like in nature, finance and computer science.
Q. 1. Which of the following sequences is an arithmetic sequence?
(a) 2, 4, 8, 16, 32, …
(b) 1, 3, 6, 10, 15, …
(c) 5, 10, 15, 20, 25, …
(d) 1, 1, 2, 3, 5, …
Ans. Option (c) is correct.
Explanation: This is an arithmetic sequence with a common difference of 5.
Q. 2. In a geometric sequence, the first term is 3 and the common ratio is 2. What is the fourth term?
(a) 12
(b) 24
(c) 48
(d) 6
Ans. Option (b) is correct.
Explanation: The fourth term is calculated as 3 × 23 = 24.
Q. 3. Which sequence is a Fibonacci sequence?
(a) 1, 4, 9, 16, 25 …
(b) 3, 6, 9, 12, 15 …
(c) 0, 1, 1, 2, 3 …
(d) 2, 5, 8, 11, 14 …
Ans. Option (c) is correct.
Explanation: This sequence follows the Fibonacci pattern where each term is the sum of the two preceding ones.
Q. 4. Explain the difference between an arithmetic sequence and a geometric sequence.
Ans. An arithmetic sequence has the same difference between each number, while a geometric sequence has the same ratio between numbers. In arithmetic, you add a number each time; in geometric, you multiply by a number each time.
Q. 5. Why are number sequences important in real life? Give an example.
Ans. Number sequences help us understand patterns in nature, finance and technology. For example,
the Fibonacci sequence appears in how leaves are arranged on a stem.

What is Case Study Question for Class 6 Maths?
Case study questions help students use maths concepts in real-life situations. These questions make students think deeply and understand the topic instead of just memorizing it. For CBSE Class 6 students, these questions connect what they learn in class to real-world problems, helping them develop better thinking and problem-solving skills.
Why Practice Case Study Questions for Class 6 Maths?
Practicing case study questions helps students:
- Understand real-life applications of mathematical concepts, such as using fractions in cooking or ratios in dividing items equally.
- Enhance problem-solving skills by analyzing scenarios and selecting the correct mathematical approach.
- Prepare for exams effectively, as these questions are now a part of CBSE’s question paper pattern.
- Build confidence in handling non-standard problems that may appear challenging at first glance.
How to Solve Case Study Questions in Maths Effectively?
Tips for students:
- Read the problem carefully: Understand the context and identify the key numbers and variables involved.
- Break the problem into steps: Tackle one part of the problem at a time to avoid confusion.
- Use the correct formula: Review the chapter’s concepts and identify the formula that fits the question.
- Double-check calculations: Avoid careless errors by re-checking your math.
- Visualize the scenario: Drawing a rough sketch or diagram can often make solving the problem easier.
