Yeap, it is 5 + 7 = 12. Thanks!

No, it is not 12. Just to give a hint: you should think of the digits (not numbers) in the left and right columns. Hope it helps!

Can you fix the equation by moving one matchstick?

My answer is choice B. This is because the numbers in the grid have a pattern within the horizontal rows. This pattern is that the last two numbers in the row are equal to the previous two numbers added together.
6 9 15 24 6+9=15 9+15=24
2 4 6 10 2+4=6 4+6=10
11 19 30 49 11+19=30 19+30=49
7 1 8 9 7+1=8 1+8=9
This pattern works with answer choice B throughout the grid of numbers, so that is my final answer.
Yeap, this is the correct answer!

These are my guesses:
First Sequence: 31
This is because I think there are two separate patterns in the sequence, with the even and odd terms. So, there is 43, 38, 34, ? and 8, 9, 11, 14. For the second sequence inside this one, you add 1, then 2, and then 3, to get the numbers in the sequence. For the first sequence now, you subtract 5, and then 4, so I guess the next time it will be by 3. This gets 34-3, which is 31.
Second sequence: 61
I thought 61, because I noticed the pattern that each term added by the last two gets the next term. For example, 0+2+3=5, 2+3+5=10, 3+5+10=18, 5+10+18=33. So, 10+18+33 equals 61. To check this, 18+33+61 equals 112, which is the last term in the sequence.
Exactly, thanks for taking the time to check!

Hello, can you find the missing numbers in each one of the below series?
43, 8, 38, 9, 34, 11, ?, 14
2, 3, 5, 10, 18, 33, ?, 112
