Organic chemistry pentagon
WitrynaC,H,,, often is represented as a regular pentagon in which it is understood that each apex represents a carbon atom with the requisite number of hydro- ... 36 2 Structural … WitrynaIn the original sequence: n=1 result=1 n=2 result=1+4 n=3 result=1+4+7 and so on. And if you look closely, each n is equal to the sum of an AP with r=3: The generic formula: Sum An = (A1+An)n/2 = (1+ (1+r (n-1))n/2 = (2+3n-3)n/2 = (3n-1)n/2. Best answer and explanation I have seen for this problem! I am very thankful to you.
