when 2 double bonds are present one after the other, it is called cumulated
when 2 double bonds are present leaving one single bond in between, it is called conjugated
when 2 double bonds are present leaving more than one single bond in between, it is called isolated
here 2 double bonds are present one after the other,
so this is cumulated
