What is the name of the random number generator used in the British television show 'Countdown'?

Hehehehehehehehehehehehehehe The sum of all natural numbers 1 to 100 can be calculated using the formula, S= n/2[2a + (n − 1) × d], where n is the total number of natural numbers from 1 to 100, d is the difference between the two consecutive terms, and a is the first term. There are a total of 100 natural numbers, so n = 100. The sum of the numbers 1-100 would be equal to the number of pairs (50) multiplied by the sum of each pair (101), or 50 x 101 = 5,050.

Waldo Lydeker, Oh wait, you mean this???? 61 reverse of 16 i.e square of 4 52 reverse of 25 i.e square of 5 63 reverse of 36 i.e square of 6 94 reverse of 49 i.e square of 7 46 reverse of 64 i.e square of 8 18 reverse of 81 i.e square of 9 So next one is 1?????

What? No comments from anyone? Everyone is so afraid of math. So, being a Mathematics major at the University of Southern California, I guess it's my duty to step up to the plate and be the first to comment. What is the next number in this sequence: 61 52 63 94 46 18 (answer: would you believe it is 1?) Don't lose sleep over it. Forgot to mention that I'm also a member of Mensa, natch.
