Were the two lengths in the complex no. Q root 13 and 3? Also, what is a quadratic series?

I got root 13 and 3 !
also, a quadratic sequence is a sequence where the second difference is always the same (like how in the question the second difference was always 2)

No I think the answer was root 13 = root 13. The answer to the first question in complex numbers was 5+i not 5i

Okay maybe that where I went wrong? Also it was 13 deliveries fr the last part of q 1?

Skelly567
Not I think it was 8 deliveries :/ that is what I got but can anyone else confirm that?
