Question

4 arithmethic mean between -2 & 23

Answer 1

What is the question?

Answer 2

WELCOME TO OPENSTUDY :D

Answer 3

\[\frac{23-2}{2}\]Unless there is more to the question.....

Answer 4

How about you try using simple examples first?

Answer 5

let b = 23 and a= -2
then d = b-a/n+1 where n = 4
therefore d = 5
so the arithmetic means are
3,8,13,18

Answer 6

AH HA! Someone that understood the question! It has been to long since I took stats.

Answer 7

Let the four arithmetic means be A2,A3,A4 and A5.
then A1,A2,A3,A4,A5,A6 is our new sequence
A1=-2 and A6=23
since An=A1+(n-1)d
A6=-2+(6-1)d=23
5d=25
d=5
so An=A(n-1)+d
A2=-2+5=3
A3=3+5=8
A4=8+5=13
A5=13=5=18.
