6 + 7 + 8 + 9 + 10 + 11 = 51
Assuming it is an addition sum - in any addition sum such as 5 + 6 = 11, the numbers 5 and 6 are called addends.
The sum of the six numbers/6 = 12 The sum of the six numbers = 72 (72-6)/6=11
17 and 6
5 and 11
11 and 5
17 AND 11
11 and 6
well, let's break it down. First, the even numbers between 1 and 11 are, 2,4,6,8,10. Now 2+4=6, 6+6=12, 8+12=20, 20+10=30. So, to answer your question simply, the sum of even numbers between 1 and 11, is 30.
83
6 9 11 23
The numbers are 5 and 6.
5 & 11 (16 - 6 = 10, 10/2 = 5 this is the lower number, 5 + 6 = 11)
