Question

Define a sequence and give an example. Choose the correct answer below. A. A sequence ​{a Subscript n ​} is an ordered list of numbers of the form ​{a 1 ​, a 2 ​, a 3 ​, ​..., a Subscript n ​, ​...}. For​ example, {1,​ 3, 5,​ ...} is a sequence. B. A sequence ​{a Subscript n ​} is a finite set of numbers ​{a 1 ​, a 2 ​, a 3 ​, ​..., a Subscript n ​}. For​ example, {5,​ 19, 400,​ 2, 17} is a sequence. C. A sequence ​{a Subscript n ​} is an infinite sum of the form a 1 plus a 2 plus a 3 plus ... equals Summation from k equals 1 to infinity a Subscript k . For​ example, 2 plus 3 plus 4 plus ... equals Summation from k equals 1 to infinity (k plus 1 )is a sequence. D. A sequence ​{a Subscript n ​} is an increasing finite set of numbers ​{a 1 ​, a 2 ​, a 3 ​, ​..., a Subscript n ​} such that a 1 less thana 2less thana 3less than...less thana Subscript n. For​ example, {2,​ 5, 17,​ 19, 400} is a sequence.

Answer 1

The correct option is A

A sequence ​{a Subscript n ​} is an ordered list of numbers of the form ​{a 1 ​, a 2 ​, a 3 ​, ​..., a Subscript n ​, ​...}. For​ example, {1,​ 3, 5,​ ...} is a sequence.

Explanation:

The right option is A.

A sequence is an ordered list of number,that could be A.P( arithmetic progression, linear sequence)

Or G.P. ( geometric progression, geometric sequence).
