List the next three terms in the following sequence:1, 9, 17, 25, 33, 41,...Also list the number that would be the twentieth number in the sequence.

Each term increases by 8: 1, 9, 17, 25, 33, 41. Adding 8 three more times gives 49, 57, and 65. The twentieth term is 1 + 19 × 8 = 153, so the correct choice is “49, 57, 65; 153.”
