Question

find 5 rational numbers between -1/2 and1/2

Answer 1

since we have to find 5 numbers between -½ and ½
1st step: Find mean of the numbers.
(-½+½)/2
=0
now we have, -½,0,½

we got one number between it,
now find mean of -½ and 0, also of 1/2 and 0

we get, -½,-¼, 0,¼,½

now find the mean between -¼ and 0
also between 0 and ¼

we get -½,-¼,-⅛,0,⅛,¼,½,

so the five numbers between -½ and ½ are
-¼,-⅛,0,⅛,¼.
