WebSolution. The given A.P. is 5, 8, 11, 14, ...... Here, a = 5, d = 8 – 5 = 3, t n = 68. Since t n = a + (n – 1)d, 68 = 5 + (n – 1) (3) ∴ 68 = 5 + 3n – 3. ∴ 68 = 2 + 3n. ∴ 66 = 3n. ∴ n = 66 3. WebSep 9, 2024 · Fourth term: a 4 =a 1 + 3d. Fifth term: a 5 =a 1 + 4d. Arithmetic sequence formula for the nth term: a n =a 1 + (n-1) Here; a n = nth term. a 1 = 1st term. n = term number. d = the common difference.

WebFinding the nth term, arithmetic sequence, and its sum. For the calculation of nth term, arithmetic sequence and its sum, you can simply use the arithmetic series calculator above. Example: Find the nth term and sum … WebPurplemath. The two simplest sequences to work with are arithmetic and geometric sequences. An arithmetic sequence goes from one term to the next by always adding (or subtracting) the same value. For instance, 2, 5, 8, 11, 14,... is arithmetic, because each step adds three; and 7, 3, −1, −5,... is arithmetic, because each step subtracts 4.
