What are the first 5 terms of the sequence generated by the formula an = 2 (n!)

2, 4, 12, 48, 240

Step-by-step explanation:

We have the recursive formula a_n = 2 * (n!)

Find:

a_1 = 2 * 1! = 2

a_2 = 2 * (2!) = 4

a_3 = 2 * (3!) = 2*6 = 12

a_4 = 2 * (4!) = 2*24 = 48

a_5 = 2 * (5!) = 2*5*24 = 240
