858251 462486 123552 218251
Subtract each of the 2nd, 3rd and 4th terms from its preceding term and
write it between and below the two terms which were subtracted:
858251 462486 123552 218251
-395767 -338934 94699
Do the same with the bottom row.
858251 462486 123552 218251
-395767 -338934 94699
56831 433633
376802
Now repeat the 376802 and place it to the right of 376802
858251 462486 123552 218251
-395767 -338934 94699
56831 433633
376802 376802
Now we work backwards. Add the 376802 to the 433633 getting 810435,
and write that to the right of the 433633
858251 462486 123552 218251
-395767 -338934 94699
56831 433633 810435
376802 376802
Add the 810435 to the 94699 getting 905134,
and write that to the right of the 94699
858251 462486 123552 218251
-395767 -338934 94699 905134
56831 433633 810435
376802 376802
Add the 905134 to the 218251 getting 1123385,
and write that to the right of the 218251,
858251 462486 123552 218251 1123385
-395767 -338934 94699 905134
56831 433633 810435
376802 376802
So the next number in the series is 1123385
