Three Possums in a Trenchcoat is correct I got the same answers as them and got 100.
except for #7 I thought it was A but when I looked at the question carefully I knew it was B.

I just realized i dropped out because if this course and this question, how time flies
1. Wrong, the pattern in the sequence is +4 hence 2+4=6+4=10+4=14 so add 4. 14+4 =18+4= 22. This makes the answer, 18 and 22.
2. Correct
3. Correct
4. I agree
5. Correct

Thanks @Three Possums in a Trenchcoat I came here to check my answers and I got them all correct!
three possums in a trenchcoat is correct.
But, letters won't help you because you might not have the same arrangement of options as the people who are submitting their answers. Which is why you need the writen answers so here.
1. Start with 2 and add 4 repeatedly.
2. Start with 2 and multiply by 2 repeatedly.
3. 15, 18, 21
4. geometric
5. 1/128
6. 25, 45, 70
7. Is your classmate adding the same number to 2 to get 3 and so on? Or is she multiplying those numbers by its ratio?
Remember when your sharing the answers make sure to include written answers.
Jojo, then look for the written answers in your second life. Trust me, it'll help.
