Out of 12 terms, the average of first 6 terms is 36 and that of last 6 terms is 42. If the average of first 11 terms is 38, find the $$12^{th}$$ term.
Total for 12 terms $$=(6\times36)+(6\times42) = 468$$
Total for first 11 terms $$=11\times38 =418$$
Therefore, 12th term $$=468-418 = 50$$
Option C is correct.
