Hi,

I am working on some Nth problems - can anyone tell me if this is correct :-

Nth term sequence is n + 4 are the first three terms

5,6,7,

A nth term is 85 - 5n are the first three terms of the sequence

17, 34, 51,

A nth term is 2n - 0.5 are the first three terms of the sequence

2.0 1.5, 1

Thank you !!

Andy
