1+48. Then add one to the first, take one from the second. 2+47. 3+46. 4+45. 5+44. 6+43. 7+42. 8+41. 9+40. 10+39. 11+38. 12+37. 13+36. 14+35. 15+34. 16+33. 17+32. 18+31. 19+30. 20+29. 21+28. 22+27. 23+26. 24+25. You get the idea.
Factors come in pairs. It is only in the case of a square number that the two middle factors are equal and so are counted only once.
It depends on what you mean by "make." If you add, subtract, or multiply two even numbers, the answer is always an even number. But if you divide, the answer is not always even: 6/2 = 3 14/2 = 7
2 + 164 + 146 + 128 + 104 pairs of even numbers can be found whose sum is eighteen.
5+5+5+5+1 That is only 5 numbers being added. There can be no answer for six numbers for the following reasons: The numbers are all odd. Two odd numbers make an even number. Two even numbers make an even number. 21 is odd. Take 6 odd numbers and add them up in pairs. Each pair of odd numbers gives an even number so there are 3 even numbers. Even + Even + Even = Even. So sum of any six odd numbers is even but 21 is not even.
2 is the only even prime number, because all other even numbers can be divided as 2.
You cannot do this, because you're taking odd numbers: if you add two odd numbers together, you will get an even number. Take the odd numbers in pairs, so you'll have 3 pairs plus an extra odd number. The 3 pairs make 3 even numbers. You can add up any number of even numbers and get an even number, so you will have an even + odd, which is odd. 30 is an even number, but your result will be odd, no matter what 7 odd numbers you choose.
The factors of all numbers can be written in pairs. With square numbers, one of those pairs is the same number twice. When listed singly, square numbers have an odd number of factors. All others are even.
All numbers can be broken down into factor pairs. No matter how many pairs there are, it's an even number of factors. Squares have a factor pair that consists of the same number twice. When you list them, you list the number once.
No, because every other even number besides 2 is composite and odd numbers are never adjacent.

There is only one even prime number, which is 2. Every other even numbers is divisible by 2, as well as by 1 and itself, so no other even number can be a prime number. Thus, the entire set of even prime numbers is the number 2.
There is only 1 even prime number which is 2
2 + 164 + 146 + 128 + 104 pairs of even numbers can be found whose sum is eighteen.

The only even prime number is 2. Other even numbers can be divided by 2, so they are composite numbers.
You have to multiply something by something else to get a product. All numbers have factors in pairs.
