Can a recursive formula produce an arithmetic or geometric sequence?

arithmetic sequence * * * * * A recursive formula can produce arithmetic, geometric or other sequences. For example, for n = 1, 2, 3, ...: u0 = 2, un = un-1 + 5 is an arithmetic sequence. u0 = 2, un = un-1 * 5 is a geometric sequence. u0 = 0, un = un-1 + n is the sequence of triangular numbers. u0 = 0, un = un-1 + n(n+1)/2 is the sequence of perfect squares. u0 = 1, u1 = 1, un+1 = un-1 + un is the Fibonacci sequence.


What is the geometric sequence formula?

un = u0*rn for n = 1,2,3, ... where r is the constant multiple.


What recursive formulas represents the same arithmetic sequence as the explicit formula an 5 n - 12?

What is the recursive formula for 2 1 3 4 7 11?

It look like a Fibonacci sequence seeded by t1 = 2 and t2 = 1. After that the recursive formula is simply tn+1 = tn-1 + tn.


Which of the following recursive formulas represents the same geometric sequence as the formula an 2 n - 1?

If you want to ask questions about the "following", then I suggest that you make sure that there is something that is following.


A certain arithmetic sequence has the recursive formula If the common difference between the terms of the sequence is -11 what term follows the term that has the value 11?

In this case, 22 would have the value of 11.


What is the formula to find the sum of a geometric sequence?

The formula to find the sum of a geometric sequence is adding a + ar + ar2 + ar3 + ar4. The sum, to n terms, is given byS(n) = a*(1 - r^n)/(1 - r) or, equivalently, a*(r^n - 1)/(r - 1)


What is the 9th term in the geometric sequence described by this explicit formula?

In order to answer the question is is necessary to know what the explicit formula was. But, since you have not bothered to provide that information, the answer is .


Can a sequence of numbers be both geometric and arithmetic?

Yes, it can both arithmetic and geometric.The formula for an arithmetic sequence is: a(n)=a(1)+d(n-1)The formula for a geometric sequence is: a(n)=a(1)*r^(n-1)Now, when d is zero and r is one, a sequence is both geometric and arithmetic. This is because it becomes a(n)=a(1)1 =a(1). Note that a(n) is often written anIt can easily observed that this makes the sequence a constant.Example:a(1)=a(2)=(i) for i= 3,4,5...if a(1)=3 then for a geometric sequence a(n)=3+0(n-1)=3,3,3,3,3,3,3and the geometric sequence a(n)=3r0 =3 also so the sequence is 3,3,3,3...In fact, we could do this for any constant sequence such as 1,1,1,1,1,1,1...or e,e,e,e,e,e,e,e...In general, let k be a constant, the sequence an =a1 (r)1 (n-1)(0) with a1 =kis the constant sequence k, k, k,... and is both geometric and arithmetic.


Will the explicit formula find the same answer when using the recursive formula?

It is often possible to find an explicit formula that gives the same answer as a given recursive formula - and vice versa. I don't think you can always find an explicit formula that gives the same answer.


Which is the recursive formula for the nth term in a geometric sequence?

You need to know two numbers to completely describe the geometric sequence: the starting number, and the ratio between each number and the previous one. When you use recursion, you always need a "base case", otherwise, the recursion will repeat without end. In words, if "n" is 1, the result is the starting term. Otherwise, it is the ratio times the "n-1"th term. The following version is appropriate for a programming language (written here in pseudocode, i.e., not for a specific language): function geometric(starting_number, ratio, term) if term = 1: result = starting_number else: result = ratio * geometric(starting_number, ratio, term - 1)
