(1 + 20) x (20/2) ie 210
0 + 1 + 1 + 2 + 3 + 5 + 8 = 20
0 + 1 + 1 + 2 + 3 + 5 + 8 = 20
8 and 1 8*1=8 8+1=9
12 and 8
8 & 12
It is 14 and 6.
The numbers are 8 and 1 .
The mean of these, or any group of ten numbers, is 1/10th of their sum.
The two numbers are 1 and 8 1*8=8 1+8=9
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.
8 times 1 = 8 8+1=9
8
