How is the RHS related to the LHS

Question

Please explain the following relationship:

Accessible:

2 --> 18
20 --> 48
200 --> 6
2000 --> 26
How did I arrive at these?

Answer 1

I think you wrote the

numbers as Roman numerals, converted to numbers using A1 - Z26, and summed

like this

2 → II → 9 + 9 = 18
20 → XX → 24 + 24 = 48
200 → CC → 3 + 3 = 6
2000 → MM → 13 + 13 = 26
