It is C=0.7n+2

I'd say treat this as a line equation instead of a sequence solving thing. If you do so, you can use the equation 'change in y/ change in x', which is

5.5-2=3.5
5-0=5
3.5/5 = 0.7. Since x is 0.7, you know that'll be n n yeah the 2 is y intercept
im guessing you got the 1 mark for having the correct y intercept value.
To double check things like this, use desmos- very helpful
