Answer:
6.8, 16.6, 26.4, 36.2
Step-by-step explanation:
Let's write the sequence, d is the common difference:
- 3, - 3 + d, - 3 + 2d, -3 + 3d, - 3 + 4d, 46
Therefore 46 = -3 + 5d
5d = 49
d = 49/5 = 9.8
So the first arithmetic mean is -3 + 9.8 = 6.8. and the second is -3 + 2(9.8) = 16.6...
They are:
6.8, 16.6, 26.4, 36.2.
