anonymous · Answer

add the two numbers up to get the next one

Do you understand what all sequences actually are?

anonymous · Answer

no

anonymous · Answer

oh that question was probably not for me was it?

anonymous · Answer

Nope, I don't.

Arihmetic will have a common difference between terms

parthkohli · Answer

Arithmetic sequence, where $a_n - a_{n -1} = \rm constant$.
Geometric, where $a_n /a_{n-1} = \rm constant$.
(What is an exponential sequence?)
Recursive, where $a_{n + 2} = a_{n+1} + a_{n}$

<chuckles>
recursive sequence, @ParthKohli ?

parthkohli · Answer

Eh?

terenzreignz · Answer

$$\large a_{n+2}=a_{n+1}+a_{n}$$
Is this a definition or an example? :3

terenzreignz · Answer

Actually a recursive sequence is one where the terms are defined as functions of their preceding terms... 
But that's technical stuff :3
