sp1214 yours doesn't quite add up .....
it works for the first few numbers:
4 ............ 8 ........... 28 ........... 80 ...........
....... 4 ........... 20 ........... 52 .............
............... 16 .......... 32 ..........
but for the next number on the bottom line to be 64, the sequence now reads:
4 ............ 8 ........... 28 ........... 80 ........... 196 ..............
........ 4 ........... 20 ........... 52 .......... 116 ............
............... 16 .......... 32 .......... 64 ............
we know that the next number on the top line is 244, so now the sequence reads:
4 ............ 8 ........... 28 ........... 80 ........... 196 .............. 244
....... 4 ........... 20 ........... 52 .......... 116 ............ 48
.............. 16 .......... 32 .......... 64 ............ -68
It's close, but it doesn't quite work with the last few numbers.
If the last number was 440 instead of 244, then it would work okay:
4 ............ 8 ........... 28 ........... 80 ........... 196 .............. 440
....... 4 ........... 20 ........... 52 .......... 116 ............ 244
.............. 16 .......... 32 .......... 64 ............ 128
I wonder if pkavitha has made a typo, cos it's weird how the last number on the 2nd line would be 244 ...... anyway my works so either I'm right (hopefully lol) or pkavitha made a typo and you're right .......
