3, -6, 12, 4, 20, 13, 27, 21, 33
-9, +18, -8, +16, -7, +14, -6, +12
8 + 4n
what is the pattern for the following 3, -6, 12, 4, 20
The sequence alternates between dividing by 2 and adding 4. Starting with 72, we divide by 2 to get 36, then add 4 to get 40, divide by 2 to get 20, and so on. Following this pattern, the next number in the sequence would be 8 (16 divided by 2).
Give the simple formula for the nth term of the following arithmetic sequence. Your answer will be of the form an + b.12, 16, 20, 24, 28, ...
The nth term of the sequence -4 4 12 20 29 is 8n+12 because each time the sequence is adding 8 which is where the 8n comes from. Then you take 8 away from -4 and because a - and - equal a + the answer is 12. Which is where the 12 comes from. Hope I helped.
The given pattern appears to alternate between two sequences: one sequence that doubles the previous number (3 to 6 to 12) and another that adds 1 to the previous number (4 to 20). Following this pattern, after 20, the next number in the doubling sequence would be 24, as it continues from 12. Thus, the next number in the pattern is 24.
8 + 4n
If you mean: 5, 10, 20, 40 then the following number is twice the previous number which will be 80
The pattern appears to be: subtract 6, add 17, subtract 14, add 9, subtract 7. Following this pattern, the next number should be obtained by adding 3 to the last number in the sequence, which is 6. Therefore, the next number in the sequence is 9.

It is neither.
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
12

The nth term of the sequence -4 4 12 20 29 is 8n+12 because each time the sequence is adding 8 which is where the 8n comes from. Then you take 8 away from -4 and because a - and - equal a + the answer is 12. Which is where the 12 comes from. Hope I helped.
