Write in set builder formA={1,5,10,15,...} |
|
Answer» The set of numbers given by you is infinite and there is no pattern in the numbers in the set, so it can not be written in set builder form. For clarity, you can read the note above example 6 of Sets which is opposite to this case..... Also the set contains element 1 your form does not satisfy it The set continues to infinity Let A be the set A={1,5,10,15}We have seen that the above set is the multiple of 5.So, The equation satisfying this set is P=5n, n is the natural number and n<3Put n=1 , P=5Put n=2, P=10Put n=3, P=15A = { 1 , 5 , 10, 15} in set builder form isA = { P :P = 5n where n<3} |
