In Excel 2007 I have a question...

I have a cell in a column B1:
MJTB1001

I need to paste to approximately 235 new rows in the column B1 as follows

MJTB2002
MJTB3003
MJTB4004... etc.

What formula should I use to accomplish this task?

Also I have the cell MJTB2044 and I need to make 235 new cells in column to
fit like this...

MJTB2044
MJTB3044
MJTB4044
MJTB5044 ... etc... 235 times....

Any thoughts?

Thank you.
