an = 4n - 14 So a35 = 35*4 - 14 = 140 - 14 = 126

-8

Even numbers.

22 they increase by 4 each time

There are some solutions where the sequence goes ... 14, 15, 13, ... but since yours goes ...,14, 1, 5, 13, ... it is not clear what the solution is.

-20, -14, 28

It is 4n+2 and so the next number is 18

-34 would be the 15th term.

The answer depends on what the explicit rule is!

What number best completes the sequence 1 1/2 5 10 1/2 18

The nth term would be -2n+14 nth terms: 1 2 3 4 Sequence:12 10 8 6 This sequence has a difference of -2 Therefore it would become -2n. Replace n with 1 and you would get -2. To get to the first term you have to add 14. Therefore the sequence becomes -2n+14. To check your answer replace n with 2, 3 or 4. You will still obtain the number in the sequence that corresponds to the nth term. :)
