{3} is a subset of {1, 2, 4, 5, 6}
true or false?

False.

Step-by-step explanation:

Since, a set is called the subset of a set if that set contains all the element of the set.

That is, B is called subset of a set A,

If Set A contains all the element of B,

Since, the element of set {3} is 3,

And, the elements of set {1,2,4,5,6} are 1,2,4,5,6

Thus, 3 is not contained by set {1,2,4,5,6}

Hence, {3}  is not a subset of set {1,2,4,5,6}

Given statement is FALSE.

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
