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

first one is correct

second:
term(1) = 85 - 5(1) = 80
term(2) = 85 - 5(2) = 75
term(3) = .... = 70

third:
term(n) = 2n - 0.5
term(1) = 2 - .5 = 1.5
term(2) = 4 - .5 = 3.5
term (3) = 6 - .5 = 5.5
Thank you ...
