The number next to 9 is 40. In this question, numbers 7, 8, and 9 have intervals of 1. In order to get the sequence for 16 and 27, you have to use the following formula: 7 plus 1 is equals to 8 multiply it by 2 = 16. For number 27, 8 plus 1 is equals to 9 multiplied by 3 = 27. Next would be 9 plus 1 equals to 10 multiplied by 4 to come up to 40. Hope this answer helps.
