Question

Consider the set S = {10, 11, 12, 13, 14, 15, …}. Show that this set has the same cardinality as the set of natural numbers. Be certain to include a description in general terms.

Answer 1

Set S has an infinite number of elements

cardinality is the number of elements

10,11,12,...

can be put in a 1 to 1 correspondence with the natural numbers

1,2,3, ....

so they're equal, both cardinality = infinity

that's a countable infinitty
