The answer for the first 30 odd numbers (1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39,41,43,45,47,49,51,53,55,57,59) is 995.Actually, the sum of the first 30 odd numbers is 900.1+3+5+7+9+11+13+15+17+19+21+23+25+27+29+31+33+35+37+39+41+43+45+47+49+51+53+55+57+59 = 900
Addition of an even number of odd numbers will always equal an even number. Take, for example, 1, 3, 5, 7, the sum of which is 16.It is impossible to add four numbers up to 27 using merely odd numbers.
This is not possible, 27 is an odd number, 4 odd numbers will always equal an even number.
27? unless you add 5 too. Then it would be 32. 7+9+11= 27 :)
To find the sum of the numbers, we must first know the value of n. This was not included in your question.
7, 9 & 11.
27, 29, 31
its 27 29 and 31
-2
The sum of the even numbers is (26 + 28 + ... + 100); The sum of the odd numbers is (25 + 27 + ... + 99) Their difference is: (26 + 28 + ... + 100) - (25 + 27 + ... + 99) = (26 - 25) + (28 - 27) + ... + (100 - 99) = 1 + 1 + ... + 1 There are (100 - 26) ÷ 2 + 1 = 38 terms above which are all 1; their sum is 38 x 1 = 38. So the difference of the sum of all even numbers and all odd numbers 25-100 is 38.
150/160
The numbers are 27, 29 and 31.

the answer of the first 4 composite numbers is 27
25 (25+27+29=81)
There is no solution. You could do it if the numbers were odd: 25 and 27 are consecutive odd numbers that equal 52.
Addition of an even number of odd numbers will always equal an even number. Take, for example, 1, 3, 5, 7, the sum of which is 16.It is impossible to add four numbers up to 27 using merely odd numbers.
