Find the sum of the following sequence : 2, 22, 222, ……… to n terms.
Input : 2 Output: 1.9926 Input : 3 Output: 23.9112
A simple solution is to compute terms one by one and add to the result.
The above problem can be efficiently solved using the following formula:
- Look-and-Say Sequence
- Gould's Sequence
- Aronson's Sequence
- Connell Sequence
- Find F(n) when F(i) and F(j) of a sequence are given
- Increasing sequence with given GCD
- Alcuin's Sequence
- Gijswijt's Sequence
- Aliquot Sequence
- k-th number in the Odd-Even sequence
- Padovan Sequence
- Golomb sequence
- Recaman's sequence
- Farey Sequence
- Juggler Sequence
