Please, I need your help.

Hi All,
Greetings to you here, I'm Lateef Odumesi, an online business expert and a programmer for that matter, I'm happy being on this forum.

Please, I'm having problem with one of my programs so I need the code to generate the sequence of random numbers after giving the input of three different numbers.
The program should be able to accept input of first, second, third and possibly fourth number then detect the formular or progression and continue the sequence.

Expample of such sequence are:
49059, 49405, 47231, 47325
another sequence: 50765, 51168, 50378
I want to know the formular and continous sequence.

Looking forward to your quick and positive response.

Thanks in anticipation for your support.
