There are infinitely many numbers between 34 and 50 and so infinitely many sets of 4 numbers.
Including 50, there are 34.
There are 34 composites.
15 prime numbers are between 0 and 50
There are 13 even numbers between 32 and 60, namely, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, and 58.
prime numbers between 40 and 50: 41, 43, 47
All even numbers other than 2 are composite, so the even composite numbers between 30 and 50 are 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, and 50.
Inclusively (counting 1 and 50) there are 50. Exclusively there are 48.
Answer vary according to the type of number. If we say, whole numbers, counting numbers or integers between 40 and 50 then the answer is 9. But, if we talk about rational numbers and irrational numbers between 40 and 50, then the answer is infinite.
21 numbers - if you include the 10 and the 50.
50
There are three prime numbers between 50 and 65: 53, 59, and 61
There are four prime numbers between 50 and 100. They are 67, 71, 73, and 79.
