  2. The first term is 17, and the pattern is to subtract 3 each time, so the term to term rule is 'start at 17 and subtract 3'. The next two terms of the sequence are 5 and 2, giving the sequence as...

  4. The 𝒏th term refers to a term's position in the sequence, for example, the first term has 𝒏 = 1, the second term has 𝒏 = 2 and so on. An expression for the 𝒏th term is worked out...

  5. To find the nth term of a sequence use the formula a n =a 1 +(n−1)d. Here’s how to understand this nth term formula. The nth term of an arithmetic sequence is given by: a_{n}=a_{1}+(n-1) d . To find the nth term, first calculate the common difference, d. Next multiply each term number of the sequence (n = 1, 2, 3, …) by the common difference.

    Consider the sequence 3, 6, 9, 12, 15, .... is an arithmetic sequence because every term is obtained by addinga constant number (3) to its previous term. Here, 1. The first term, a = 3 2. The common difference, d = 6 - 3 = 9 - 6 = 12 - 9 = 15 - 12 = ... = 3 Thus, an arithmetic sequence can be written as a, a + d, a + 2d, a + 3d, .... Let us verify ...

    The above formula for finding the nth term of an arithmetic sequence is used to find any term of the sequence when the values of 'a1' and 'd' are known. There is another formula to find the nth term which is called the "recursive formula of an arithmetic sequence" and is used to find a term (an) of the sequence when its previous term (an-1) and 'd'...

    Let us take an arithmetic sequence that has its first term to be a1and the common difference to be d. Then the sum of the first 'n' terms of the sequence is given by Sn = a1 + (a1 + d) + (a1 + 2d) + … + an... (1) Let us write the same sum from right to left (i.e., from the nthterm to the first term).

  6. There are three things needed in order to find the 35 th term using the formula: the first term ( [latex]{a_1}[/latex]) the common difference between consecutive terms ([latex]d[/latex]) and the term position ([latex]n[/latex] ) From the given sequence, we can easily read off the first term and common difference.

  7. The sequence formulas include the formulas of finding the nth term and the sum of the first n terms of a sequence. Understand the sequence formula with derivation, examples, and FAQs.
