Question

Could you explain restrictions to the domain and range of a sequence.(arithmetic and geometric sequence) please...

Answer 1

@perl

Answer 2

been stuck on this for a while. :(

Answer 3

For me it is easiest to think of sequences as functions with domain of integers.
for example the sequence f(n) = 2*n, lets assume the domain is n=1,2,3,..
that gives us the sequence
2*1, 2*2, 2*3, 2*4, ... 2*n , ...

Answer 4

okay, so here are my numbers 3,6,9 and 4,8,16

Answer 5

still there @perl?

Answer 6

yes

Answer 7

3,6,9 can be represented by the rule f(n) = 3*n
the domain will be 1,2,3 in that case

Answer 8

have any ideas? i'm very lost...

Answer 9

oooohhhh, i get it thank u soooo much @perl :)
