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.
