Hi, in this question given number is 650 base 7.
00:07
We need to find the preceding and succeeding term of 650.
00:13
We know that here base is 7.
00:17
So the number lies between 0, 1, 2, 3, 4, 5, 6.
00:27
So when we reach the digit 6, it go immediately to 10, that is 0 .1, 2, 3, 4, 5, 6.
00:33
07, 17, 27, 37, 37, 7, 7, 7, 7.
00:42
After 6, it automatically goes 10 -7.
00:46
Again 11 -7, 12 -7, 13 -7, 14 -7, 15 -7, 15 -7, 16 -7.
00:55
Again it goes to 27.
00:59
7...
