anonymous · Answer

yes

hero · Answer

Hint: 
`T' is the set of numbers that are not even`

amistre64 · Answer

then any option with a 2 in it is bad

amistre64 · Answer

Hero, that is an assumption :)  a valid assumption tho

hero · Answer

Why is it merely an assumption?

amistre64 · Answer

the best we can go for is that S contains elements that are not in T; so the empty set is out

amistre64 · Answer

i can create many sequences that start out as 2,4,6,8

amistre64 · Answer

one of those is the set of positive evens; but without a specific rule, all we can do is assume

amistre64 · Answer

We know that T' has at least 1,3,5,7 in it so it cant be empty; that only leaves the third option as valid enough :)
