For example take the four times table
and add a Three card to each pile.
Calculating the resulting numbers give this sequence of cards
We have taken a hand in the four times table and
added three to the hand .
This is recorded as 4x + 3, with the result depending on the declared value for x.
As it is based on the four times table we note that each number in the sequence is four more than the previous number.
This leads to two new puzzles.
- Given a sequence of numbers find out if it is a disguised times table and find the hand that would play the sequence.
- From a maths record of a disguised times table find the declared value of x.
