WebFind n th term N th term of an arithmetic or geometric sequence The main purpose of this calculator is to find expression for the n th term of a given sequence. Also, it can identify if the sequence is arithmetic or geometric. The calculator will generate all the work with detailed explanation. N th term of an arithmetic and geometric sequence WebFeb 3, 2024 · The n -th term should be n − 1 ∑ i = 0(n(n − 1) 2 + 1 + i)3 . The first summand is obviously in accordance with what we know and if we compute the last summand of the above expression we get (n(n − 1) 2 + 1 + n − 1)3 = (n(n − 1) 2 + n)3 = (n(n + 1) 2)3 , which is what we expected.
WebJun 19, 2016 · Explanation: The formula for n th term of a geometric sequence is arn−1 where a is the first term and r is the common ratio. In the given sequence first term is 1 and the common ratio is 2. Hence nth term would be 2n−1 Note that r = a term previous term = 2 1 = 4 2 = 8 4 = 16 8 = 2 Answer link
