Question

Find the 11th term of following AP 7,13,19,25​

Answer 1

Answer:

67

Step-by-step explanation:

an =a+(n-1)d

a= 7

d = 13-7 =6

a11= 7+(10)*6

a11= 7+60

a11= 67

Answer 2

Answer:

AP = 7,13,19,25....

Given : Common difference = 13 - 7 = 6 = d

            First term = 7 = a

To find : 11th term = $a_{11}$

Formula : $a_{n} = a + (n-1)d$ (where $a_{n}$ is nth term of AP)

Solution :

$= a_{11} = a + (11-1)d\\\\= a_{11} = 7 + (10)6\\\\= a_{11} = 7 + 60\\\\= a_{11} = 67$
