Question

MATHEMATICIANS, CHALLENGE YOURSELF TO THIS QUESTION
MEDAL AND FAN TO THAT PERSON WHO WILL ANSWER THIS CORRECTLY
IF YOU ANSWER THIS CORRECTLY, YOU TRULY KNOW MATH

Answer 1

Wait..I will post the question.

Answer 2

Me too

Answer 3

\[c(2n)=c(n) \rightarrow c(2n+1)=-1^{n}c(n) \rightarrow c(1)=1 \rightarrow \sum_{i=1}^{2013}\]

Answer 4

What is the summation?

Answer 5

@phi @hartnn

Answer 6

Somewhat wild guess, but -1.

Answer 7

Can you show your work for evidence?

Answer 8

The sequence will be entirely negative ones and ones. From math team work, this means that the final sum will probably be -1, 0, or 1 (Not really a mathematical fact, just something that you learn after 6 years of questions like this)

Answer 9

what do the arrows mean

Answer 10

can you clairfy your question, are you giving me 4 equations and saying what would the summation have to be?
