Question

What could be a subset of this set-
{5, 10, 15, 20, 25,...}

hartnn · Answer

what are your choices?

anonymous · Answer

i dont have any im suppose to creat one for it

hartnn · Answer

ok, subset means a set whose elements are all from given universal set, but is of smaller(or equal) size than the universal set.

hartnn · Answer

your universal set is a set of integers which are multiples of 5

hartnn · Answer

u can make a subset in which there are integers which are all multiples of 10
like {10,20,30,...}
did u understand this ?

anonymous · Answer

not really

hartnn · Answer

which part ?

anonymous · Answer

all parts tbh

hartnn · Answer

did u read what i wrote for subset... subset means.....
did u try to understand that?

anonymous · Answer

yes i read it an i tried to understand, wat ur saying is that a subset is a set made from all elements in the universal set?

hartnn · Answer

yes, here universal set is given to be {5, 10, 15, 20, 25,...}
so we pick some of the elements from this and form a subset, i picked alternate elements like 10,20,30...and formed a set of integers which are multiples of 10
got this ?

anonymous · Answer

ahhhhh the light bulbs are finally going of

hartnn · Answer

off? means u did not understand ?

anonymous · Answer

so u create a subset from some of the elements of a universal set aka the original set

anonymous · Answer

srry it sounded wrong i meant i am finally understandin

hartnn · Answer

yes, and its ok.

hartnn · Answer

can u create one more subset using same logic , for me ?

anonymous · Answer

yah sure srry i just saw ur last comment

anonymous · Answer

20,40,60,80,100,...

anonymous · Answer

does that work @hartnn

hartnn · Answer

absolutely! 
multiples of 20 
similarly  u can create subsets which are multiples of 15,25,30,40, ....and so on

anonymous · Answer
