Find the missing number in the following sets of number.? 13 499 17 6913 11 59

To find the missing number in the given set, we need to look for a pattern or rule that governs the sequence of numbers.

Looking at the numbers, we can see that they are not in any particular order. However, we can observe that all the numbers are odd.

If we take a closer look, we can see that each number is obtained by multiplying the previous number by a prime number. For example, 13 is obtained by multiplying 11 (the previous number) by 1 (the prime number). Similarly, 499 is obtained by multiplying 13 by 17, and so on.

Using this pattern, we can find the missing number. To do this, we need to find the prime number that, when multiplied by 59 (the previous number), gives us the next number in the sequence.

Let's calculate it step by step:

59 * 1 = 59 59 * 3 = 177 59 * 5 = 295 59 * 7 = 413 59 * 11 = 649 59 * 13 = 767 59 * 17 = 1003

From the calculations, we can see that the missing number is 1003.
