1000,2250,4000,?"

• 2250-1000=1250
  4000-2250=1750
  
  1750-1250=500,hence deference of deference is 500
  then 1750+500=2250 and
  2250+4000=6250
  ans=6250

• 1000,2250,4000 all are factors of 250
  
  250*4=1000
  250*9=2250
  250*16=4000
  
  since 4,9,16 goes in the order 2^2,3^2,4^2
  so the next no will be 5^2 i.e 25
  
  so the next number is
  250*25=6250

  (1000+2250)/2 = 1625
  (2250+4000)/2 = 3125
  (4000+x)/2 = 4625
  x=9250-4000=5250.

• 1000*2+250=2250
  2250*2-500=4000
  4000*2+250=8250

• (1000/4)*5=1250
  1250+1000=2250
  (4000/4)*5=5000
  5000+4000=9000
  so ans 9000

• 1000/250=2^2
  2250/250=3^2
  4000/250=4^2
  ____/250=5^2---->6250

• 10^2*10 = 1000
  15^2*10 = 2250
  20^2*10 = 4000
  answer 25^2*10 = 6520 (increment 5 in every step)

• 1000=10^2 *10
  2250= 15^2 *10
  4000=20^2 *10
  6250=25^2 *10
  
  so ans is 6250

• the common factor among the numbers is 250,so dividing it in even and odd series we can have for the odd series 2000 and 5000.dividing 1000 by 250 we have 4,dividing 4000 by 250 we have 16,again in the odd series 2250/250=9,then
  [(16-4)+9]*250=5250.

• Check the diff b/w first two solutions1625 & 3125. Same diff for next one 4625 & 3125 is 1500.
  Solve it [4625*2]=9250, then solve x=5250

• 2250-1000=1250
  4000-2250=1750
  x-4000=2000
  x=2000+4000
  x=6000

• 1000-2250=1250 NOW WE HAVE ADD 500 TO 1250 WE GET 1750.
  2250-4000=1750 NOW WE HAVE ADD 500 TO 1750 WE GET 2250
  4000-?(X) =2250------FROM THIS X=4000+2250
  =6250
