If a = -1, d = -3 in an A.P, then 12th term is A) 17 B) -23 C) -34�

1.	If a = -1, d = -3 in an A.P, then 12th term is A) 17 B) -23 C) -34 D) -17
Answer» Correct option is (C) -34 \(a=-1,d=-3\) \(\therefore a_{12}=a+11d\) \(=-1+11\times-3\) \(=-1-33=-34\) \(\therefore\) \(12^{th}\) term is -34. Correct option is C) -34

If a = -1, d = -3 in an A.P, then 12th term is A) 17 B) -23 C) -34 D) -17

Answer»

Correct option is (C) -34

\(a=-1,d=-3\)

\(\therefore a_{12}=a+11d\)

\(=-1+11\times-3\)

\(=-1-33=-34\)

\(\therefore\) \(12^{th}\) term is -34.

Correct option is C) -34
