WebThe equation for calculating the sum of a geometric sequence: a × (1 - r n) 1 - r Using the same geometric sequence above, find the sum of the geometric sequence through the 3 rd term. EX: 1 + 2 + 4 = 7 1 × (1-2 3) 1 - 2 = -7 -1 = 7 Fibonacci Sequence WebN 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
Web1 1 , 3 3 , 9 9 , 27 27 , 81 81 , 243 243. This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 3 3 gives the next term. In other words, an = a1rn−1 a n = a 1 r n - … WebQuestion: Write an expression for the nth term of the sequence: 4, 10/3, 28/5, 82/7, 244/9, a. an = 3n-1/4n b. an = 3n +1/2n-1 c. an = 3n -1 /2n-1 d. an = 3n +1/2n+1. Write an expression for the nth term of the sequence: 4, 10/3, 28/5, 82/7, 244/9, a. a n = 3 n-1 /4 n . b. a n = 3 n +1/2n-1. c. a n = 3 n -1 /2 n-1 .
WebSo, let's start by seeing if 3n works as a formula for the nth term: When n=1, 3n=3, which is not a term in our sequence. Step 2) If we subtract 1, we get 2, which is a term in our sequence. Step 3) So, the nth term is "3n-1". Let's check this: For n=3, 3n-1=9-1=8, which is … WebFind the first for terms of the sequence whose nth term is an = 2 + 3n.

WebThe divergence test is a conditional if-then statement. If the antecedent of the divergence test fails (i.e. the sequence does converge to zero) then the series may or may not converge. For example, Σ1/n is the famous harmonic series which diverges but Σ1/ (n^2) converges by the p-series test (it converges to (pi^2)/6 for any curious minds).
