An infinite number ofd them. 251, for example, or 251.3256.
This is expressed as 250< n < 330 and covers any number in the range 251 to 329. If 250 and 330 are to be included in the range then the expression is written 250 ≤ n ≤ 330.
You can calculate the number halfway between 250 and 330 by adding them together, then divide by 2. For example, 250 + 330 = 580, and 580 divided by 2 = 290, which is the number halfway between the two numbers.
370
The average of 330 and 410 is 370.
They are already in least to greatest order. 203, 250, 302 and 330.
The number directly in the middle of 175 and 250 is (175 + 250)/2 = 212.5
The number half-way between 125 and 150 is (125 + 250) / 2 = 187.5.
330 is one such number.
It is 200
It is: 227.5
(150 + 250) / 2 = 200
A number that is between 200 and 250 divisble by 3 not 2 is 249
