Question

Write a recursive sequence that represents the sequence defined by the following explicit formula:

Answer 1

kmkmlklm

Explanation:

Answer 2

0,-2,-4,-6,-8, ...

Explanation:

In order to find the sequence represented by the given explicit formula we have to plug in the values of n

Given formula is:

`a_n=2-2n\\a_1=2-2(1)\\=2-2=0\\a_2=2-2(2)\\=2-4\\=-2\\a_3=2-2(3)\\=2-6\\=-4\\a_4=2-2(4)\\=2-8\\=-6\\a_5=2-2(5)\\=2-10\\=-8`

So the explicit sequence is:

0,-2,-4,-6,-8,..........
