Rational numbers between 1 and 5

1. 3 2. 2 3. 0 4.infinite 5.finite.

• rational no. between any two no. a & b is always infinite.
  
  can be calculated by (a+b)/2 then [(a+b)/2 + a]/2 etc

• It is an alternate series
  focus only on odd places.....
  1 2 3 4 5, so definately, Ans=6

• If m and n be two rational numbers such that m < n then 1/2 (m + n) is a rational number between m and n.
  here
  1/2(1+5)=3
  1>3>5
  again rational number between 1 and 3 = 1/2(1+3)=2
  and between 3 and 5= 1/2(5+3)=4
  1>2>3>4>5
  total 3 rational numbers lies between 1and 5

• we have to find rational numbers between 1 and 5
  formula=(a+b)/2
  (1+5)/2=3;
  now 1
