The next number in the sequence is 27. To get the next number, double the number and add one. Except for the second number, all the numbers in the sequence follow this rule.

times 2 plus 2 minus 1 repeated so it would be 15, 30, 32

To get the number to complete the sequence, multiply the first number to 3 and then add 2 to get the next number. Given 1, 5, 17, 53, 161 ____Solution:1 x 3 (+2) = 55 x 3 (+2) = 1753 x 3 (+2) = 161161 x 3 (+2) = 485Therefore, the number to complete the sequence is 485.
