1st picture) seasonal trend because the data shows a pattern that is repeated yearly and is increasing
2nd picture) not sure between random trend and structural changes

the residual shows no clear pattern as the data points are scattered above and below the line therefore the relationship is linear

p.s. this question could go under the 'VCE Further Maths Question Thread!' as it is not a time series question anymore  :D

Looks like there's a slight pattern in my opinion. At least at the start.
