Anybody can teach me how to interpolate?

Question

For example, you have a table, gives you a value of A=10 if B=20 and A=15 if B=30. So it doesn't give you the value of B if A=12 or the vaue of A if B=26 because it' just not in the table. If you can give some kind of formula or procedure on how to interpolate I would appreciate it. Thanks.

Answer 1

ok so u double hte value of A

b = 2A

or if u have b then u halve it to get A
