• Given that flowers in pond gets doubled every day
  Consider flower on 1st day=1
  1,2,4,8,16.....
  The above series is in GP with a=1 and r=2 & given pond fills in 20th day
  therefore Sn=a(r^n-1)/(r-1)=1(2^20-1)
  Pond gets half on 19th day,numbers of flowers=2^19-1

• On 29th Day
  Because on 29th day it will fill half the pool and on 30th day it will get double
