array iteration problem

[r1998]

Dear friends and respected seniors,
I have the following data in column A, starting from A2
100
200
250
300
100
350
550
400

What I am trying to do is I compare A2 with A3 . If A3<=A2+100 , then compare A2 with A4 and so on......
If A3>=A2+100 , use that cell instead of A2 and compare with the lower cells.....means compare A3 and A4 and so on
i have used this formula in column B

= IF( A3>=A2+100,A3,"")

and this in column c

= IF( A3>=$A$2+100,A3,"")

but i am getting incorrect results.
this is the link of screenshot of my excel sheet

I have manually entered the required results in column D.

Can anyone please kindly guide me as to how I can achieve the results of column D.
Awaiting your replies.
Thank you.
