RE: What is an Arithmetic Progression? (Let's Learn Series #24 - Math)
Thank you, dear student 😉
Is 'D is x squared minus 1' the answer for the 3rd question?
I'll give the results right away after you tell me which question.
By the way Kenny, thanks a lot for answering these questions. You might know these before I taught you but I really appreciate your flexibility to spend some time to answer my Qs and to support me :D
Well, that WAS my answer for the third one, but I see now that it doesn't work! :)
And I'm not sure what the right answer is. Unless the 4th number is 31 instead of 35. Then I would have an answer. :) But you stumped me with 3, 7, 15, 35!
Whoops... the pattern should be 3, 7, 15 and 31 instead of 35 as I remember. You've got it right! By the way, we can't take it as an Arithmetic progression. Because the difference is not the same.
Congrats! You've received 2/3 marks! Thanks again for the support :D
