If the sequence is 205, 306, 427 then a possible 4th number is 568.
The initial difference between 205 and 306 is 101, which increases by 20 at each step.
306 → 427 = 121 : 427 → 568 = 141
It could be: 2*214 = 428
18
The number which best completes the sequence below is 20 5 30 6 42 7
27.
The best choice for the next term after those shown is 75 .We have no way to know whether or not that will 'complete' the sequence.
864
27 BUT, as far as I can tell, it does not complete the sequence which can continue further.
It could be: 2*214 = 428
18
27. But that continues the sequence, it does not complete it.
One.
The number which best completes the sequence below is 20 5 30 6 42 7
27.

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.
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.
