19
They are 15, 16, 17, 18 & 19.
24, they are going up in 3's, 13, 16, 19 and 18, 21 so next number is 24.
35
When you subtract a negative number, it has the same effect as adding a positive number. Therefore, in this instance, 16 - (-3) = 16 + 3 = 19.
-3
The amount between each number doubles. Between 16 and 19 = 3 Between 19 and 25 = 6 Between 25 and 37 = 12 Between 37 and 61 = 24 Therefore, the next in the sequence would be: 109
19
The question is: What are the prime numbers between 16 and 32? We must first remember what a prime number is. A prime number is a number that can only be divided by 1 fand also by itself. So the numbers between 16 and 32 that can only be divided by 1 and itself are 17, 19, 23, 29, and 31.

The mass number of an atom is the sum of its protons and neutrons. Since sulfur has 16 protons (its atomic number) and 19 neutrons, the mass number of a sulfur atom with 19 neutrons would be 16 + 19 = 35.
The number midway between 19 and 53 is 36.
Expressed as a mixed number in its simplest form, 19/16 is equal to 1 3/16 or one and three sixteenths.
19, because since you know sulfur has 16 protons because that's its atomic number. you do 35-16=19
19 is prime.
20 is the next number greater than 19. The next prime number greater than 19 is 23.
A number which has more than two factors is called a composite number. Factors of 16 are 1, 2, 4, 8 and 16. As we can see that 16 has more than two factors so, it is a composite number. Whereas 19 is prime because it has only two factors: 1 and 19.
