You are thinking of two numbers whose sum is 64 If you double the second and subtract this product from the first the result is -8 What are the two numbers?

Firstly: X + Y = 64
Secondly: X - 2Y = -8
Therefore X = 2Y - 8
Now, we can put that value of X into the first equation and we get 2Y - 8 + Y = 64
Which reduces to 3Y = 72, and that gives Y = 24.
So, if X + 24 = 64 then X = 40.
Putting that into the second equation we get: 40 - 2(24) = 40 - 48 = -8

Why is it that when you subtract four consecutive numbers the answer is always double the highest number but in minus?
Clarify. Subtract four consecutive numbers ... from what? It appears you mean something like: 22 - 21 - 20 - 19 And the answer is NOT -44. It is -38 ... negative double of the LOWEST number. If this is what you mean, then you have discovered another rule of mathematics. It will always work. 1001 - 1000 - 999 - 998 = -1996 Exactly the negative double of 998
If you know the average and product of two numbers how do you find the answer?
What's the question ? Is it to find what the two numbers are ? Since you know their average, you know what the sum of the two numbers is. It's double their average. Now you know their sum, and you know their product. Take the product, and list all of its factors. Find two of the factors that add up to the sum of the two numbers. Those are probably the two numbers you're looking for.

How does this work Pick a number any number add 17 double it subtract 4 double it add 20 divide by 4 and subtract 20 You end up with your original answer. How?
Start with n, then you get; Add 17: n + 17 Double it: 2n + 34 Subtract 4: 2n + 30 Double it: 4n + 60 Add 20: 4n + 80 Divide by 4: n + 20 Subtract 20: n which is where you started.

How do you write C program to print a Series of Odd Numbers and Even Numbers.?
Generate a random number in half the range you are interested in. If generating odd values, subtract 1 from the upper bound of the range. That is, if the range is 0 to 100, then generate a random number in the range 0 to 50 for even numbers and 0 to 49 for odd numbers. Double the generated number to obtain the even value, or double it and add 1 to obtain the odd value.
