Can anyone help?

===========================================================

A master criminal has broken into a jeweller`s strong room which has the walls lined with several thousand storage boxes protected by individual four digit combination lock codes.. Each storage box contains small bags of precious stones (diamonds etc.) so the total value of all the contents of the locked boxes in this room is several million of ££s .

Each box is labelled with a letter and three digits and the thief knows that the combination lock code for each individual box can be calculated from this sequence.

Eg ...........

**Box**No

**T176**has a Combination Lock

**Code**of

**6896**

However , each box has this Combination Lock Code engraved on the INSIDE and fortunately several of these boxes are empty and have been left OPEN . This means that the criminal can now list each open Box Number with its own Security Code , and , using this information will attempt to work out the method of calculating any Security Code from its Box Number.

The aim is to open two particular boxes which contain the most valuable bag of diamonds

So the question is .

"What is the code for boxes

**W456**and

**R588**?"

Here is the list of open

**BOX**numbers with their security

**CODES**from inside.

Can you workout ( and explain ! ) the method to determine the combination lock code of Boxes

**W456**and

**R588**

**BOX CODE BOX CODE BOX CODE**
