The arithmetic mean of 10, 11, and 6 is 9. Add them together then divide by 3.
The arithmetic mean is (22 + 31 + 34)/3 = 87/3 = 29The arithmetic mean is (22 + 31 + 34)/3 = 87/3 = 29The arithmetic mean is (22 + 31 + 34)/3 = 87/3 = 29The arithmetic mean is (22 + 31 + 34)/3 = 87/3 = 29
-1 deduct 3 each time
2+3+5+7+11 = 28/5 = 5.6
1/2 (3x + 1 + x - 3) = 1/2 (4x - 2) = 2x - 1
The average or mean of 3, 5, 7, 9, and 11 is 7.
The arithmetic mean of 10, 11, and 6 is 9. Add them together then divide by 3.

2+3+5+7+11 = 28/5 = 5.6
Arithmetic mean is simple averages of numbers that you have. e.g if you 4 numbers as 2,3,5,1 then arithmatic mean of these number is 2+3+5+1 divided by 4. so arithmatic mean for above numbers is 11/4=2.75
1/2 (3x + 1 + x - 3) = 1/2 (4x - 2) = 2x - 1
This is the real question what is the 19th term in the arithmetic sequence 11,7,3,-1,...? _________________________________________________________ Looks like you just subtract 4 each time, as : 11,7,3,-1,-5,-9, ......
4 and one-seventh
It is the start of an arithmetic sequence.
