Neither the next term nor the general term of the whole sequence can be determined explicitly by just judging at a listing of a finite number of (the first few) terms. It'll go back down in about 3 days. These differences have a second difference of 2 (i.e. 4! Explanation: Having the first term of the sequence a(0) = 3 a(1) = 3 + 5 = 8 We realized that a(1) = a(0) + 2 2 +1 We also have : a(2) = a(1) + 2 3 +1 = 8 + 7 = 15 a(3) = a(2) + 2 4 +1 = 15+ 9 = 24 From above we can realize that each term is the sum of the previous term and 2* (sequence coefficient added to 1) and 1 So the nth term will be: its dual problem is Minimize w = 10y1 + 8y2 #a(3) = a(2) + 2*4 +1= 15 +9 =24#, From above we can realize that each term is the sum of the previous will be ???n+3???. Find the Nth term of the series 1, 3, 7, 15, 31 . 2, 2, 2, 2,.. This sequence goes on forever, it's like a modified Fibonacci sequence. How much would an order of 1 slice of cheese pizza and 3 sodas cost? are negative, ???a_n??? Share your suggestions to enhance the article. in what place did david finish? Student Academic Success offers personalised support, workshops and online resources to help you develop the skills you need to succeed in your studies. As @Ethan points out in the comments, mathematicians prefer fractions over decimals, one should convert the sequence in the form $$\dfrac{5}{4},\dfrac{8}{4},\dfrac{13}{4},\dfrac{20}{4},\cdots$$ So it is easy to spot . ?, the value of the sequence is ???-4??? ?if so, find its 6th term. Similarly, the term at nth position of the pattern will be n21. #" "# 2, 8, 4, 3, 4, 3, 11. The fifth term of an arithmetic sequence is 23 and the 12th term is 72. See also: General Webster's Revised Unabridged Dictionary, published 1913 by G. & C. Merriam Co. Which of the following is correct? It's recursive, it depends on the previous number. Find the mean proportion between 4 and 16? N th term of an arithmetic and geometric sequence 35+13=48 as the next number. #" "# I'm having some difficulty understanding finding patterns to the nth degree. 31 is the Dutch country code and (0)81 is actually reserved for free information services, though (081) is not, Sorry for a tangent but I wonder if anyone ever asks a question, what is the general formula for 01-31-81-151-241, and get an answer "It's obviously $(n^2-1)''1$".
