Oh, dude, let me put on my math hat for a sec. So, to find a number between 1100 and 1200 that's divisible by 11 and 13, we need to find the least common multiple of 11 and 13, which is 143. Then we just need to find which multiple of 143 falls within the given range. So, the number you're looking for is 1147. Boom, mathed it!

The missing number is 26. The number after 29 is 58.

13 is an unlucky number.
The missing number is 26. The number after 29 is 58.
That would be -5.
The spacing is 6 1+6=7 7+6=13 13+6=19 19+6=25 so the missing number in the sequence is 13
