If the nth term of an A.P, is 2n + 5, its first term is A) 0 B) 7 C

1.	If the nth term of an A.P, is 2n + 5, its first term is A) 0 B) 7 C) 2 D) 4
Answer» Correct option is (B) 7 Given that \(n^{th}\) term of A.P. is 2n+5. \(\therefore a_n=2n+5\) \(\therefore\) First term is \(a_1=2\times1+5\) \(=2+5=7\) Correct option is B) 7

If the nth term of an A.P, is 2n + 5, its first term is A) 0 B) 7 C) 2 D) 4

Answer»

Correct option is (B) 7

Given that \(n^{th}\) term of A.P. is 2n+5.

\(\therefore a_n=2n+5\)

\(\therefore\) First term is \(a_1=2\times1+5\)

\(=2+5=7\)

Correct option is B) 7
