Question

Make a conjecture about the next item in the sequence 6, 18, 19, 57, 58

Answer 1

Continuing from 58: 174, 175

Explanation:

The pattern is multiply by 3, and add 1. 6 x 3 = 18, and 18 + 1 = 19. same pattern works for 19 times 3, and 57 times 1. 57 times 3 is 174, then add the 1 to get 175
