5/7,18/11,09/11,15/08,13/15,12/15,17/19,09/02,?

• two series present
  one is 5/7,9/11, 13/15, 17/19, x/(x+2)
  it looks like 5,7,9,11,13,15,17,19,so numerator is 21 and then denominator is 23
  ans is 21/23

• Odd sequence gets incremented by 4 and even sequence decrements by 3
  I.e
  5+4/7+4=9/11
  18/11%18-3/11-3=15/8
  Soon....
  Ans is 21/23 ie 17+4/19+4

• in each series, the difference between the two number in numerator and denominators are same order,
  hence after compairing difference b/t two no,s, the next series is = 21/23

• Ans. 21/23
  
  The odd positions forms a series, 5/7, 9/11, 13/15, 17/19, ...
  In every consecutive term, the numerator and the denominator is larger by 4 from the numerator and the denominator of the previous number.
  Following this the next number would be (17+4)/(19+4) = 21/23

• odd sequence is in the sequence of odd numbers 5,7,.... so the last one will be 21/23 since 21 is the next odd number to 19

• 5/7,18/11,09/11,15/08,13/15,12/15,17/19,09/02
  the numbers at 1,3,5...(odd position) are x+4/(y+4)
  the numbers at 2,4,6,....(even position) are z-3 / (pattern of one 7 then 11 is repeated after one digit the other one is repeated).
  so the next numbers are 21/23, 6/2

• for the alternative numbers, both the numerator and denominator is add with 4
  let us take 1st term and 3rd term,
  numerator:5+4=9
  denominator:7+4=11
  same logic should be apply for all the alternative numbers
  ans:21/23

• answer=21/2
  5/7,18/11,9/11,15/8,13/15,12/15,17/19,9/2,?
  skip 18/11,9/11,skip,13/15,17/15,skip,9/2,6/2(so denominator is 2)
  and numerator is based on this (5/7,9/11,13/15,17/19,?) 5+4=9,9+4=13,13+4=17,17+4=21
