If you mean that the number continues by a number of 0s which is one more than the previous numbers of 0s followed by a 2 forever, then it is an irrational number. If you mean that the "2020020002" repeats then it is a rational number.
Suppose the least number is x. Then the greatest is 2x and the middle is x+3. So x + (x+3) + 2x = 75 ie 4x+3 = 75 or 4x = 72 or x = 18 So the three numbers are 18, 21 and 36.
2x + 5 =
8+2n
11,33
18 and 6
The numbers are: 48+22 = 70
Type your answer here... 3 and 82
The two numbers are 15 and 31. 15 + 31 = 46.
If the larger number can be anything more than twice the smaller number, then the two numbers can be:1 + 45 = 463 + 43 = 465 + 41 = 467 + 39 = 469 + 37 = 4611 + 35 = 4613 + 33 = 4615 + 31 = 46

Three more than twice a number.

When we say that a number varies by a factor of two from another number, it means that one number is twice the value of the other. Mathematically, if we have two numbers, A and B, and A varies by a factor of two from B, then A = 2B. This relationship indicates that A is double the value of B.
You will need to explain the question in more detail. What do you mean by finding the mean of a number? The mean of a number is just that number. Did you intend the mean of a set of numbers? And if so, how many?
The numbers seem to be 61 and the dirty Gertie, blind 30.
