WebThe n -th term of an arithmetic sequence is of the form an = a + (n − 1)d. In this case, that formula gives me a_6 = a + (6 - 1)\left (\frac {3} {2}\right) = 5 a6 = a+(6−1)(23) = 5. Solving this formula for the value of the first term of the sequence, I get a = -\frac {5} {2} −25. Then: a1 = -\frac {5} {2} −25 WebExpert Answer. Given,a1=3, d=−7The first te ….

WebFirst, find the common difference of each pair of consecutive numbers. 15−7 = 8 15−7 = 8 23−15 = 8 23−15 = 8 31−23 = 8 31−23 = 8 Since the common difference is 8 8 or written as d=8 d = 8, we can find the next term after 31 31 by adding 8 8 to it. Therefore, we have 31 + 8 = 39 31 + 8 = 39. Example 2: Find the next term in the sequence below. Weba = 1 (the first term) d = 3 (the "common difference" between terms) And we get: {a, a+d, a+2d, a+3d, ... } {1, 1+3, 1+2×3, 1+3×3, ... } {1, 4, 7, 10, ... } Rule We can write an …
