A) A group of numbers arranged in a specific order
B) A set of random numbers
C) Numbers that are not related to each other
D) A sequence is not a mathematical concept
Answer: A
Explanation: A sequence is a list of numbers arranged in a specific order, where each number is related to the others by a defined rule.

2) What is the common difference in the arithmetic sequence: 3, 7, 11, 15, ...?
A) 2
B) 3
C) 4
D) 5
Answer: A
Explanation: The common difference is found by subtracting any term from the next term (7 - 3 = 4).
---
3) In a geometric sequence, if the first term is 2 and the common ratio is 3, what is the second term?
A) 6
B) 8
C) 9
D) 11
Answer: A
Explanation: The second term is found by multiplying the first term by the common ratio (2 ร 3 = 6).
---
4) What does the sigma notation represent in mathematics?
