Here,the number is multiplied by 4 successively to get the next result.

$25 \times 4 =100$

$100 \times 4 =400$

$400 \times 4 =1600$

$1600 \times 4 =6400$

 

Hence,Option(A)$400$ is the correct choice.

The pattern is as follows:

  • $25*4=100$
  • $100*4=400$
  • $400*4=1600$
  • $1600*4=6400$

Another observation:

The given series is a completely divisible series. each number is div by 4.

Hence option (A) 400 is correct.
