What are the two whole numbers closest to 162

We can assume the numbers are 161 and 163
it can also be showned by adding and subtracting the numbers by 1.

For example.
Numbers refering to 2; 1 and 3
To solve this equation we can first assume that both a and b are nonzero real numbers. Hence, A = 1 b = 1 
1.   2 (1) + 1 = 3
2.    2 + 1 = 3:
3.    3 - 1 = 2


Numbers refering to 100; 99 and 101
To solve this equation we can first assume that both a and b are nonzero real numbers. Hence, A = 1 b = 1 
1.   2 (1) + 1 = 3
2.    99 + 1 = 100:
3.    101 - 1 = 100
