The statement describes an arithmetic progression, which is defined by following formula:
(1)
Where:
- First element of the sequence.
- Progression rate.
- Index of the n-th element of the sequence.
- n-th element of the series.
If we know that ,
and
, then the progression rate is:
The set of elements of the series are described by .
Lastly, if we know that , then the 300th term of the sequence is:
And the next three terms of the sequence are:
n = 5
n = 6
n = 7
The next three terms of the sequence are 17, 21 and 25.
The 300th term of the sequence is 1197.
