If the first term of an A.P is -2 and common difference is -5, then 12

1.	If the first term of an A.P is -2 and common difference is -5, then 12th term is A) -32 B) 32 C) -57 D) 34
Answer» Correct option is (C) -57 First term of A.P is a = -2, Common difference of A.P. is d = -5 \(\therefore a_{12}=a+11d\) \(=-2+11\times-5\) \(=-2-55=-57\) \(\therefore\) \(12^{th}\) term is -57. Correct option is C) -57

If the first term of an A.P is -2 and common difference is -5, then 12th term is A) -32 B) 32 C) -57 D) 34

Answer»

Correct option is (C) -57

First term of A.P is a = -2,

Common difference of A.P. is d = -5

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

\(=-2+11\times-5\)

\(=-2-55=-57\)

\(\therefore\) \(12^{th}\) term is -57.

Correct option is C) -57
