The formula for finding rational numbers b/w and b=  (a+b)/2
let us find three rational numbers b/w -1 and 2:
 (i) (-1+2)/2 = 1/2
(ii) (-1+1/2)/2 = (-1/2)/2 = -1/4
(iii) (1/2+2)/2  = (5/2)/2  = 5/4
the three rational numbers b/w -1 and 2 are 1/2, -1/4, 5/4
similarly , let's find three rational numbers b/w 3 and 5:
(i) (3+5)/2 = 8/2 = 4
(ii) (3+4)/2 = 7/2 = 3.5
(iii) (4+5)/2 = 9/2 = 4.5
three rational numbers b/w 3 and 5 are 4, 3.5 and 4.5
