Question

2,__,26 are the term of arithmetic progression , its middle term is​

Answer 1

Step-by-step explanation:

First term a= 2

Difference d?

Third term = 26

so we can write a+2d= 26

2+2d = 26

2d = 26-2

2d= 24

d= 12

Means the difference is 12, so the A.P will be

2, 14, 26, 38....

Answer 2

Answer:

14

Step-by-step explanation:

First term = 2

d = x

Third term = 26

$26 = 2 + x(3 - 1)$

$26 - 2 = 2x$

$2x = 24$

$x = 12$

Common difference = 12

Second term = 2 + 12 × (2 - 1) = 2 + 12 = 14
