How do you find an arithmetic sequence
WebTo do so, you must start with the arithmetic sequence formula: tn = a + d(n −1) Then, sub in all known values. tn = 15 (last term of the sequence), a = 1 (first term), d = 2 (difference between terms) and solve for n like so: 15 = 1 + 2(n −1) Expand and simplify: 15 = 1 + 2n − 2 16 = 2n n = 8 → Therefore, the series has 8 terms.
