I know that the second one the fourth one and the fifth one are arithmetic but I’m not sure about the others I think there are only three but don’t count me on it
the mean is adding all them together and dividing by how many there are
2+3+5+6+1+10 = 27
there are 6 numbers so 27/6 = 4.5
mean = 4.5
Hmmm idk if you want fractions but, 65/24 or 2 17/24 I think
