The rule "1 less than 3 times the number" makes this equation:
3x-1
1st number: 3 * (5) - 1 = 15 - 1 = 14
2nd number: 3 * (14) - 1 = 42-1 = 41
3rd number: 3 * (41) - 1 = 123 - 1 = 122
4th number: 3 * (122) - 1 = 366 - 1 = 365
3x-1
1st number: 3 * (5) - 1 = 15 - 1 = 14
2nd number: 3 * (14) - 1 = 42-1 = 41
3rd number: 3 * (41) - 1 = 123 - 1 = 122
4th number: 3 * (122) - 1 = 366 - 1 = 365
