Which pattern can describe the numbers 2,4,10,28, and so on?

A. For each number after first, add 4 to previous number in the list.
B. For each number after first, multiply the previous number by 3 and subtract 2.
C. For each number after first, add 2 or 6 to previous number.
D. For each number including the first, multiply by 2,3,4, and so on.

I chose answer C. Is that the correct answer? If not please explain what I did wrong.

Please help! Is my answer correct?

well, does C work?

2+2=4
4+6=10
10+2=28? Nope
10+6=28? Nope

You can see the numbers grow at an increasing rate. So, A and C cannot work.

D is clearly wrong, so let's try B.

3x2-2 = 4
4x3-2 = 10
10x3-2 = 28
Looks like B to me.

what is this answer multiply 8 by 9, then multiply 4 by the result

To determine the pattern that describes the given numbers, we can analyze each option:

A. For each number after the first, add 4 to the previous number in the list.
Using this pattern:
2 + 4 = 6
6 + 4 = 10
10 + 4 = 14
This pattern does not match the given numbers.

B. For each number after the first, multiply the previous number by 3 and subtract 2.
Using this pattern:
2 * 3 - 2 = 4
4 * 3 - 2 = 10
10 * 3 - 2 = 28
This pattern matches the given numbers.

C. For each number after the first, add 2 or 6 to the previous number.
Using this pattern:
2 + 2 = 4
4 + 6 = 10
10 + 2 = 12
This pattern does not match the given numbers.

D. For each number including the first, multiply by 2, 3, 4, and so on.
Using this pattern:
2 * 2 = 4
4 * 3 = 12
12 * 4 = 48
This pattern does not match the given numbers.

Based on the analysis, option B is the correct answer as it matches the given numbers. Therefore, you chose the correct answer. Well done!
