If fractions and decimals don't scare you, then there are an infinite number
of squares in any range.
If you only want to hear about whole numbers, then there are five squares
in that range:
22 = 4
32 = 9
42 = 16
52 = 25
62 = 36
There are 2 prime numbers between 30 and 40: 31 and 37.
There are 2*13 = 26 natural numbers between them.
37
The square root of 31 falls between the whole numbers 5 and 6.
2 5 7 11 13 17 29 37 41
Halfway between 37 and 143 is the mean average of 37 and 143: (37 + 143) ÷ 2 = 90
75 - 1 = 74 numbers between 1 and 75. Divide 74 by 2 = 37 even numbers.
31 & 37
There are 2 prime numbers between 30 and 40: 31 and 37.
The halfway point between two numbers is found by calculating the average of the two numbers. In this case, the average of 37 and 111 is (37 + 111) / 2 = 74. Therefore, 74 is halfway between 37 and 111.
1 & 2
There are 2*13 = 26 natural numbers between them.
37
The square root of 31 falls between the whole numbers 5 and 6.
2 5 7 11 13 17 29 37 41
There are 16 square numbers between 1 and 300: 2 to 17 inclusive. There is no square root of these numbers: only of their sum or product or average or some other operation.
The numbers 0 and 1 fall in between the two square roots of 140.
