3) The answer to the 3rd question is quite similar to the 2nd one but slightly harder to find. I found this by attempting it 4 times. This is one of my many attempts: 5,8,13,21,34,55 added together is 136. Then you divide it by four, which is 34- you might notice that this is the second last number in your sequence, this is the answer.
Another example, in case you're not sure, here it is:
1 + 1 + 2 + 3 + 5 + 8 = 20 divided by 4 is 5, which is the second last number!
8 + 13 + 21 + 34 + 55 + 89 = 220 divided by 4 is 55, once again, the second last number!
