(C) The relation followed in the given set $(21, 51, 15)$ is:$(3rd 	ext{ term} 	imes 2) + 21 = 2nd 	ext{ term}$.Calculation: $(15 	imes 2) + 21 = 30 + 21 = 51$.Now,check the options:$A: (5 	imes 2) + 5 = 15 
eq 10$.$B: (5 	imes 2) + 13 = 23 
eq 18$.$C: (5 	imes 2) + 17 = 27$.$D: (25 	imes 2) + 20 = 70 
eq 15$.Wait,re-evaluating the logic: $(2nd 	ext{ term} - 1st 	ext{ term}) / 2 = 3rd 	ext{ term}$.$(51 - 21) / 2 = 30 / 2 = 15$.Checking option $C$: $(27 - 17) / 2 = 10 / 2 = 5$. This matches.Therefore,option $C$ is correct.
