It you add up all the digit in the number they will total 11. For example the number 425 has digits that sum to 11. (4 + 2 + 5 = 11)
656+5=1165/13=5
29 2 * 9 = 18 2 + 9 = 11 18 - 11 = 7
Use the formula for the sum of an arithmetic sequence. Start with 11, end with 99; the interval is 2.
The number is 23.
1 + 1 = 2 The sum of the digits is therefore 2.

22, 2+2= 4 and half of 22 is 11 which is odd
656+5=1165/13=5
29 2 * 9 = 18 2 + 9 = 11 18 - 11 = 7
The divisibility rule for 22 is that the number is divisible by 2 and by 11. Divisibility by 2 requires that the number ends in 0, 2, 4, 6 or 8. Divisibility by 11 requires that the difference between the sum of the the digits in odd positions and the sum of all the digits in even positions is 0 or divisible by 11.
