The positive integer cubed numbers up to 500 are:
13 = 1
23 = 8
33 = 27
43 = 64
53 = 125
63 = 216
73 = 343
The next cube number above 500 is: 83 = 512
The sum of the first 500 odd numbers is 250,000.
The sum of all the odd numbers between 1 and 499 is 62500, because there are 125 pairs adding up to 500. 125 x 500 = 62500
There are 125 such numbers.
The best trick for this is to think of averages. Put the 1 with 500, 2 with 499,, 3 with 488, ... On average these numbers are (1 + 500)/2 or 250.5 So you want to add up 500 numbers each of which is, on average 250.5 The answer is 500 x 250.5 which is 125250
1 = 1³ 8 = 2³ 27 = 3³ 64 = 4³ 125 = 5³ 216 = 6³ then next 343 = 7³ but is out of range requested
The cubed numbers up to 100 are: 1, 8, 27, 64.
There is an infinite number of prime numbers after 500!
The sum of the first 500 odd numbers is 250,000.
They are 0, 1 and 8.
4*5*5*5 = 500
The sum of all the odd numbers between 1 and 499 is 62500, because there are 125 pairs adding up to 500. 125 x 500 = 62500
There are 417 of them and it would take too long to list them all. You could draw up a list of all 500 numbers and then delete each multiple of 6. There are 83 of them.
There are 22 of those. The biggest one is the square of 22, which is 484. It's easy for you to build your own list of all of them. -- Write down a list of the numbers from ' 1 ' to 22 . Then, one at a time . . . -- Multiply the number on your list by itself, and write the result next to it. -- When you finish doing that for all 22 numbers, you'll have the list of all square integers up to 500.
Sum of first n numbers = n/2(n +1) = 500 x 1001 = 500500
There are 125 such numbers.
