    12 = -2 + 4d 14 = 4d 3.5 = d -2 + 3.5 = 1.5 1.5 + 3.5 = 5 5 + 3.5 = 8.5 1.5, 5, and 8.5 are the three arithmetic means.

    It's okay so to find the three arithmetic means, you need to subtract the two numbers. 12 - (-2) = 14 and then divide the difference by how many means you want plus one, since it is three, you need to divide it by four; 14/4 then add this factor to your lower limit -2 + 14/4 -8/4 + 14/4 (getting the lcd) = 6/4 or 3/2 (first arithmetic mean) for your second arithmetic mean, just add the factor to your first arithmetic mean 6/4 + 14/4 = 20/4 or 5 (second arithmetic mean) 20/4 + 14/4 = 34/4 or 17/2 (third arithmetic mean) to check if you were able to got the right answers, add the factor to your last arithmetic and the sum should be your upper boundary. 34/4 + 14/4 = 48/4 or 12
