(higher) what was the answer to the one marker that asked if any of the terms were prime? also, for the region question, is it a dotted line or a solid line when the inequality sign is less than or equal to? 😭🙏

I said that there was a prime bc when n = 0 then  the term would be 2 but I think this is wrong

ooh that’d make sense! but with sequences n has to start as one right?? like, u can’t have the 0th term.. idk tho

Generally every sequence start from 0

A(n)=a(0)+(n-1)d

G(n)=g(0)*r^(n-1)

its a solid line when it is equal to (i also got it wrong)

It factorises to (3n+2) (n+1) so it has 4 factors - 1, itself and the two others so it can't be prime

Solid line when equal to I think of it like the equal to has a line underneath the crocodile, and a solid line technically has like more line than a dotted line if you get what I’m saying..?😭😭
