Answer 1

Hope u like my process
======================.
The last digit is 3 times the first and 2 times the second number

Thus the last digit is a multiple of 2 and 3.

So, within 0- 9, only 6 is a multiple of 2 and 3"

Thus the last term is 6

Middle term is 6/2 = 3

1st term is 6/3 = 2


So the required number is 236..
