WebThe position-to-term rule (or the \(nth\) term) of an arithmetic sequence is of the form \(an + b\). eg: \(5n − 1\) or \(-0.5n + 8.5\) are the position-to-term rules for the two examples … WebThere is a formula for finding the nth term of an arithmetic sequence: t n = a + (n-1)d where tn represents the nth term. a represents the first term. n represents the number of terms. d represents the common difference between the terms. In your sequence, a = 5, and d = -3. Since we are looking for an expression for the nth term, we leave n as ...
WebJan 24, 2013 · a n = c 1 s n + c 2, where c 1 and c 2 are specific constants. In the problem s = 1 / 2. Therefore, a n = c 1 ( 1 / 2) n + c 2. Taking into account a 0 = 4 and a 1 = 3, one can obtain c 1 = 2 = c 2. Hence, a n = 2 1 − n + 2.
