Comments

Once we get past the first few terms, it is interesting to see the values 420, 140, 840 repeat, at least for the first 30 or so terms.

Examples

			The first two weird numbers, 70 and 836, yield 836 - 70 = 766. Similarly, the second two weird numbers, 836 and 4030, yield 4030 - 836 = 3194.
