Mathematical explorations on the sequence of factoriangular numbers: Extending the results on generalizations	2025	14	.pdf	application/pdf	7059	420	74	A generalization of the sequence of n-factoriangular numbers [19] is the sequence {𝐹𝑡𝑛,𝑘} for natural numbers 𝑛, 𝑘 ≥ 1, which follow the form 𝐹𝑡𝑛,𝑘 = (1 ⋅ 2 ⋅ 3 ⋅⋅⋅ 𝑛) + (1 + 2 + 3+. . . +𝑘 = 𝑘(𝑘 + 1)/2 for natural numbers 𝑛, 𝑘 ≥ 1.	cache/easat-5378.pdf	txt/easat-5378.txt
