find a closed form for the given sequence [0,0,0,1,2,4,8,16,.....]​

Answers

Answer 1

The closed form of the sequence [0,0,0,1,2,4,8,16,.....]​ is [tex]a_n = 2^{n-1}[/tex]

How to determine the closed form?

The sequence is given as:

[0,0,0,1,2,4,8,16,.....]​

Remove the leading zeros

[1,2,4,8,16,.....]​

The above sequence is a geometric sequence, with the following parameters:

First term, a₁ = 1Common ratio, r = 2

The closed form is calculated using:

[tex]a_n = a_1 * r^{n-1}[/tex]

Substitute the known values

[tex]a_n = 1 * 2^{n-1}[/tex]

Evaluate the product

[tex]a_n = 2^{n-1}[/tex]

Hence, the closed form of the sequence [0,0,0,1,2,4,8,16,.....]​ is [tex]a_n = 2^{n-1}[/tex]
