Answer 1

A sequence will be arithmetic if there's a constant difference between terms.

The first sequence is not arithmetic, since the differences between the terms of the sequence are


`4-3=1,6-4=2,10-6=4,18-10=8`

A sequence is geometric if there's a constant scaling factor being applied to each successive term. To determine if such a constant is there, take the ratio of successive terms.

The first sequence is also not geometric, because the ratios of consecutive terms are


`\frac43,\frac64=\frac32,\frac{10}6=\frac53,(18)/(10)=\frac95`

So the first sequence would be assigned (N), which rules out options B and D. Do the same for the next two sequences, which are the only ones you'd need to check.
