Question

find the 11th term of the AP: -3 , - 1/2 , 2 , .......

Answer 1

Answer:

given ap, -3, -1/2, 2

a1= -3

a2= -1/2

a3 =2

d= a2-a1 = -1/2 -(-3l

= 5/2

a11 = a+10 d

-3 + 10(5/2)

= -3+ 25

=22

hope it helps.....

Answer 2

$\underline{\underline{\blue{\textbf{Step - By - Step - Explanation : -}}}}$

To Find :

• 11th term of AP

Solution :

• AP : -3 , -1/2 , 2...

First term (a) = -3

common difference (d) = -1/2 -(-3)

= -1/2 + 3

= 5/2

an = a + (n - 1)d

a11 = -3 + (11 - 1) × 5/2

a11 = -3 + 10 × 5/2

a11 = -3 + 25

a11 = 22

Hence

• 11th term of AP is 22
