So i have been looking at the sequences for so long. I have come to the conclusion that the number you swap should create the smallest prime number possible when you add up all the numbers in the sequence (this is what i thought the pattern was). However when i run my code i get the error... [1,1,1] should equal [1,1,2]... i thought it would be [1,1,3] (as the total 5 would be prime) So i am completely stumped and in dire need for some assitance. I cant crack the sequence :(

How do you know which number to replace and what the replacement number should be?

Hi.

I'm not a very mathsy person. Therefore i am confused as to how you calculated x=-108.21, y=-66.64 in your seccond example. I understood the first example of how you got 14 but i am completely lost when you apply it to the 2-dimensional plane. I guess i don't know how to work well with the vectors and radiuses. Perhaps you could point me to some material that i need to learn to understand how to do this calculation or if you could offer any help it would be much appreciated.

Thanks.
