The best line graph for this pattern?

Question

Hey, :-)

Just wondering what the best pattern to go by on the line graph would be for this pattern,
(6),10,14,18,22....

Not sure what to go up by.. :-/
It has to be the best alignment to best represent this pattern

Answer 1

6,10,14,18, 22, ....

A(n) = 4n + 2 ← a straight line

Answer 2

a straight line up and to the right of your graph would be best..

Answer 3

y=4x+6

UNLESS the 6 is x=1

if it is,, then y= 4x+2

not sure what the (6) meant
