# The sequence

Level pending

Look at the following sequence. The sequence occurs infinitely for any integer.

$\ldots , 0,0,4,12,24,40, 60, \ldots$

Find the value of the difference between the $$n^\text{th}$$ term and the $$-(n+1)^\text{th}$$ term of this sequence.

Clarifications :

• The value of the sequence is "0" only for 2 terms, $$-1$$ and $$0$$
• Suppose for example take the sequence $$-2, -1, 0, 1, 2, 3, 4, 5$$, and let $$2^{nd}$$ term be $$4$$, then $$-(2+1)^{th}$$ term is $$-2$$, then your answer would be $$4-(-2) = 6$$
• The terms of the sequence is in ascending order
