Remember distributive property
a(b+c)=ab+ac
we can ervers it

6(31)+6(4)-6(15)=6(31)+6(4)+6(-15)=6(31+4-15)=6(20)=120

Find the four arthmetic means between -3 and 46

Citrus2011 [14]

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.
