The last sequence you will explore in our number sequence calculator is the star numbers, another class of figurate numbers where each term indicates the size of a collection of items you can arrange in a six-pointed star fashion. There is a neat formula to calculate the nth term of this sequence: s_n = 6\cdot n \cdot (n-1) + 1 sn = 6 ⋅ n ⋅.
