It is not possible to determine an nth term from a single number.

Nth term With the nth term you substitute the n for the term number (e.g. 50) so the 50th term in 2n+3 would be 2x50+3=103

A single number, such as 491625 does not define a sequence and so cannot have an nth term.

241688

The nth triangulat number is n*(n+1)/2 The 100th is 100*101/2 = 5050
