WebAug 15, 2024 · In this concept we will find the common difference and write n t h term rule given any two terms in the sequence. Let's find the common difference, first term and n t h term rule for the arithmetic sequence in which a 7 = 17 and a 20 = 82. We will start by using the n t h term rule for an arithmetic sequence to create two equations in two ... 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
WebJust use the standard form -> nth term= a1 + (n-1)* (D) in this case. 100th= 15 + (100-1) (-6) 100th= -579. where d is the common difference, a1 is the first term and n is the number of terms, then you'll never loose track of … WebMay 28, 2015 · 1 Answer. George C. May 28, 2015. It depends on the type of sequence. If the sequence is an arithmetic progression with first term a1, then the terms will be of the form: an = a1 +(n −1)b. for some constant b. If the sequence is a geometric progression with first term a1, then the terms will be of the form: an = a1 ⋅ rn−1.
WebNov 5, 2024 · The formula for the nth term of the sequence is the one you have already mentioned. Also rightly so you have identified that it will lead to an inefficient algorithm and stack overflow. You can look into dynamic programming approach where u calculate F(I,N) just once and just reuse the value. WebMar 7, 2024 · Using a recursive definition, you must find all of the previous terms before you could find the n th term. As an explicit definition, we would write it as: an = 7*2n-1 [for n>0] Using an explicit definition, you may find a term directly. For example, the 5 th term in this sequence, a 5 = 7*2 5-1 = 7*2 4 = 7*16 = 112. Upvote • 0 Downvote.
