This sequence is the same as the one that is given in Example 2. There we found that a = -3, d = -5, and n = 50. So we have to find the sum of the 50 terms of the given arithmetic series. S n = n/2 [a 1 + a n] S 50 = [50 (-3 - 248)]/2 = -6275. Answer: The sum of the given arithmetic sequence is -6275.

- Find the next term in the arithmetic sequence: 3, 7, 11, 15, ?. Solution. First, we have to find the common difference of each pair of consecutive numbers
- Find the next term in the sequence: 28, 23, 18, 13, ?. Solution. We start by finding the common difference: $latex 13-18=-5$ $latex 18-23=-5$ $latex 23-28=-5$
- Find the following two terms in the arithmetic sequence: -17, -13, -9, -5, ? , ?. Solution. At first glance, we may think that we have a negative common difference since we have negative numbers, but we have to remember that when the sequence is growing, the common difference is positive
- In an arithmetic sequence, the first term is 8 and the common difference is 2. Find the value of the 10th term. Solution. We begin by writing down the information given
Sequence. A Sequence is a set of things (usually numbers) that are in order. Each number in the sequence is called a term (or sometimes "element" or "member"), read Sequences and Series for more details. Arithmetic Sequence. In an Arithmetic Sequence the difference between one term and the next is a constant.
Arithmetic Sequence: Definition and Basic Examples. An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence. The constant difference in all pairs of consecutive or successive ...
For example, Sequence A: 2, 4, 6, 8, 10 Although 2 \times 2=4, this does not work for the rest of the terms. Since this sequence is arithmetic, the rule from term to term is +2. Always check all terms before deciding the rule. Thinking arithmetic sequences with negative terms always decrease If the common difference is negative, this is true.
Nov 5, 2024 · d is a common difference between any two consecutive terms of Arithmetic Sequence; Arithmetic Sequence Examples. Here are some examples of arithmetic sequences, Example 1: Sequence of even number having difference 4 i.e., 2, 6, 10, 14, . . . , Here in the above example, the first term of the sequence is a 1 =2 and the common difference is 4 = 6 -2.
