COMMENTS
No other term, between 500051 and 1000000, but integers such as 1000001, 2000002, 3000003, ..., or 50000050 will be in the sequence.
EXAMPLE
Example : 101 is in the sequence, because 0^2 + 1^2 + 10^2 + 101^2 = 10302 = 102*101
Example : 351 is in the sequence, because 1^2 + 3^2 + 5^2 + 35^2 + 51^2 + 351^2 = 127062 = 362*351
