Question

6. The 10th term of an A.P. 5,9,13, .............. is
A) 36
B) 31
C) 41
D) 21​

Answer 1

Answer:

Option c is the best option for the question

Answer 2

Given ,

First term = 5

Common difference = 9-5 = 4

We know that , the nth term of an AP is given by

$\sf \large \fbox{ \fbox{ a_{n} = a + (n - 1)d}}$

So ,

$\sf \hookrightarrow a_{10} = 5 + (10 - 1)4 \\ \\\sf \hookrightarrow a_{10} = 5 + (9)4 \\ \\\sf \hookrightarrow a_{10} = 5 + 36 \\ \\\sf \hookrightarrow a_{10} = 41$

Hence , the 10th term of AP is 41
