• in the given series divide the 15625 by 25 then we get 625 now add one 0 atlast to that number then it is 6250
  same way
  6250/25=2500
  2500/25=1000
  1000/25=400
  400/25=160
  so missing number is 400

• 
  ans 400
  15625/5=3125*2=6250
  6250/5=1250*2=2500
  2500/5=500*2=1000
  1000/5=200*2=400
  400/5=80*2=160

• ANS b)400
  160 * 5/2 =400(our ans)
  400 * 5/2 =1000
  1000 * 5/2 = 2500
  2500 * 5/2 = 6250
  6350 * 5/2 = 15625

• ANS :: 400
  
  15625/5 = 3125*2 =6250
  6250/5 = 1250*2 =2500
  2500/5 = 500*2 =1000
  1000/5 = 200*2 =400
  400/5 = 80*2 =160.
  
  So ans is 400.

• 400
  2500=1000*2+500(1000/2)
  6250=2500*2+1250(2500/2)
  160*2+80=400
• 11 years agoHelpfull: Yes(0) No(0)
• 160+160=320
  and half the 160=80
  then 320+80=400(ans)
  400+400=800
  and half of 400=200
  then 800+200=1000(ans)
