I am assuming this is homework so here is some pseudo-code...

Code:
A) Start with a shebang line.

0) Zero a file if you want to to save it all. Ignore this line if you don't want a file...

1) Use a "for" loop that starts at 0, ends at 100000 and with a jump of 25.
2) Inside this loop "append" the zeroed file with each iteration. Ignore this line if you don't want a file...
3) Print the result(s) with or without newlines inside the terminal window.

Now searching this site AND Google are your friends...

EDIT, 16:00 UK local time:-

As others have already shown differing methods I will show you yet another using "seq 0 25 100000" as shown by balajesuri:-
Code:
#!/bin/bash
> number.txt ; for n in $( seq 0 25 100000 ) ; do printf "$n\n" >> number.txt ; printf "$n\n" ; done

SEQ(1)								   User Commands							    SEQ(1)

NAME
seq - print a sequence of numbers SYNOPSIS
seq [OPTION]... LAST seq [OPTION]... FIRST LAST seq [OPTION]... FIRST INCREMENT LAST DESCRIPTION
Print numbers from FIRST to LAST, in steps of INCREMENT. Mandatory arguments to long options are mandatory for short options too. -f, --format=FORMAT use printf style floating-point FORMAT -s, --separator=STRING use STRING to separate numbers (default: ) -w, --equal-width equalize width by padding with leading zeroes --help display this help and exit --version output version information and exit If FIRST or INCREMENT is omitted, it defaults to 1. That is, an omitted INCREMENT defaults to 1 even when LAST is smaller than FIRST. The sequence of numbers ends when the sum of the current number and INCREMENT would become greater than LAST. FIRST, INCREMENT, and LAST are interpreted as floating point values. INCREMENT is usually positive if FIRST is smaller than LAST, and INCREMENT is usually negative if FIRST is greater than LAST. FORMAT must be suitable for printing one argument of type 'double'; it defaults to %.PRECf if FIRST, INCRE- MENT, and LAST are all fixed point decimal numbers with maximum precision PREC, and to %g otherwise.
