D. The Palindrome trick

A palindrome is a number, which reads the same forward and backward, e.g. 635336.

Here is a trick to find such numbers.

Choose a 3-digit number and add together

Continue the process until you get a palindrome

See the example given example

                597                  1392                 4323             

           +   795                +2931               +3234

                1392               4323                7557     a palindrome

          

E. A fancy number pattern

Write any four digits, repeating the first digit at the end (Say 26892)

                                        2 6 8 9 2

                                       4 2 1 7 4

                                      2 1 6 3 2

                                      1 5 3 1 1

Find the difference     4 2 2 0 4

Between each pair      2 0 2 4 2

Of digits and write      2 2 2 2 --- fancy number

Each answer below the

Pair as shown on the right.

Always repeat the first digit of each row at the end of that row.

Continue this process until you get a row of the same number.
