If f(1)=6, f(x)=f(x-1) • 3, what are the first 5 terms of this sequence?

Question

If f(1)=6, f(x)=f(x-1)•3, what are the first 5 terms of this sequence?

Answer 1

Hi Sophie,

 

 The key idea here is the current term is multiplied by 3 to get the term that comes after it.

 

So, term 1 is 6

and term 2 is 6*3

thus, term 2 is 18

 

term 3 is 18*3

thus, term 3 is 54

 

I'll leave it up to you to use to finish the pattern to get terms 4 and 5.
