∙ 11y ago6*10^9 / 2*10^3 = (6/2) * 10^9 / 10^2 = 3*10^(9-3) = 3*10^6 or 3 million.
1, 2, 5, 6, 9, 10, 13, 14, 17, 18, 21, 22, 25, 26, 29, 30, ... Add one, then add three, and repeat.
eight the 5 numbers add up 6 + 6 + 9 + 9 + 10 = 12 + 18 + 10 = 40 then divide by that 5 so 40 / 5 = 8
Any number can be an arithmetic mean. SO just pick any three numbers between -2 and 12. And if you want to find a set of numbers for which your selected number is a mean add 1 and subtract 1 from it, or add 2 and subtract 2 from it (or do both). Suppose you pick 8. Add 1 and subtract 1: 7 and 9. 8 IS the arithmetic mean of 7 and 9. Add 2 and subtract 2: 6 and 10. 8 is the arithmetic mean of 6 and 10. It is also the AM of 6, 7, 9 and 10.
12-13-15 etc.... The sequence is add 1 then add 2

if you mean 9/10 + 3/5 then multiply 3/5's numerator and denominator to get 6/10, which you can add to 9/10 to get 15/10, or 3/2. 1 1/2 if you need mixed numbers.
9 + 6 - 2 + 7 - 10 = -4
1+9 2+8 3+7 4+6 5+5
2/3 = 4/6 4/6 + 5/6 = 9/6 = 1 and 1/2 5 + 5 = 10 10 + 1 and 1/2 = 11 and 1/2
