Question 1100673: Madam, Sir,
Very interested in logic tests, I recently devoted myself to high iq tests. Most remain very difficult to solve.
By doing a search on the oeis database, I had hoped to find the list of sequences to study in order to solve the various high iq and very high iq tests, but my research remains unsuccessful and, I have not get any more information by contacting Neil Sloane, the founder of the oeis.
I apologize if I allow myself to bother you and to solicit your benevolence but, I will be very grateful if you would bring me more answers.
Thanking you for your attention, please accept with my greatest respect, Madam, Sir, the assurance of my respectful consideration and gratitude.
Perret Mike

Question 1101505: In the absence of friction, a freely falling body will fall about 16 feet the first second, 48 feet the next second, 80 feed the third second, 112 feet the fourth second, and so on. How far has it fallen during:
a. the seventh second?
b. the nth second?
I am incredibly confused on how to write this problem out. I know that speed times the time equals distance, but this is a sequence not a linear equation, which is a harder concept for me to grasp so if you could show how to do this problem so that I can write it out and figure it out myself that would be wonderful.

Question 1102021: In the arithmetic sequence given below, what term is the number negative 15?
5,10 thirds, 5 thirds,...
I am stuck after getting the difference which is the second term subtracted by the first term, which is negative 5 thirds. I know the formula for getting the answer for the missing term that being an=a1+(n-1). So I tried figuring out this one on my own, but end up with weird numbers, which is typical of doing arithmetic sequences that involve fractions. Also by the way the first term is 5 and the second term is 10 thirds.

Question 1102214: https://imgur.com/a/T75gw
At a total loss.
I thought, A = {-3} B= {-3, -2}
Exclude common terms, leaving -2 then exclude -3; because of the complement requirement, so all terms NOT within B.
Or would I first find the complement...then do the subtraction? So confused...
