Let the place count be
Let the th term be
Given
We are also told that any one term is the previous term + .
This is derived from where is the previous term.
Consequently we have an Arithmetic sequence with common difference of +
From this the sequence is:
→← given value
→
→
→

so, the value of is

And so on. Also from this we also have an alternative equation for any an in that we have:
