What is the fifteenth term? (b) How many terms of this sequence make the sum zero? Medium. Open in App. Solution. WebDefinition 1: A mathematical sequence in which the difference between two consecutive terms is always a constant and it is abbreviated as AP. Definition 2: An arithmetic sequence or progression is defined as a sequence of numbers in which for every pair of consecutive terms, the second number is obtained by adding a fixed number to the first one.

WebThe sum of the first n terms of an arithmetic sequence is called an arithmetic series . Example 1: Find the sum of the first 20 terms of the arithmetic series if a 1 = 5 and a 20 = 62 . S 20 = 20 ( 5 + 62) 2 S 20 = 670. Example 2: Find the sum of the first 40 terms of the arithmetic sequence 2, 5, 8, 11, ⋯ . First find the 40 th term: WebAn arithmetic sequence is a sequence (list of numbers) that has a common difference (a positive or negative constant) between the consecutive terms. 1.)7, 14, 21, 28 because Common difference is 7. 2.) 48, 45, 42, 39 because it has a common difference of - 3. 1.) 2,4,8,16 is not because the difference between first and second term is 2, but the ... date of presidential election in nigeria
