WebThe Sequence Calculator finds the equation of the sequence and also allows you to view the next terms in the sequence. Arithmetic Sequence Formula: a n = a 1 + d (n-1) … WebDec 28, 2024 · a = a₁ + (n-1)d. where: a — The nᵗʰ term of the sequence; d — Common difference; and. a₁ — First term of the sequence. This arithmetic sequence formula applies in the case of all common differences, whether positive, negative, or equal to zero. Naturally, in the case of a zero difference, all terms are equal to each other, making ...

WebAn arithmetic sequence is a sequence of numbers in which each term is obtained by adding a fixed number to the previous term. It is represented by the formula a_n = a_1 + … WebGiven a term in an arithmetic sequence and the common difference find the recursive formula and the three terms in the sequence after the last one given. 23) a 21 = −1.4 , d = 0.6 24) a 22 = −44 , d = −2 25) a 18 = 27.4 , d = 1.1 26) a 12 = 28.6 , d = 1.8 Given two terms in an arithmetic sequence find the recursive formula. 27) a 18 ... WebThis arithmetic sequence has the first term {a_1} = 4 a1 = 4, and a common difference of −5. Since we want to find the 125 th term, the n n value would be n=125 n = 125. The following are the known values we will plug into the formula: Example 3: If one term in the arithmetic sequence is {a_ {21}} = - 17 a21 = −17 and the common difference ... reagso
