Step-by-step explanation:

Answer 2

Given:-

First Term (a) = 2

Ninth Term=26

To Find:- Common Difference (d)

Solution:- We know the Formula:- a+(n-1)d

So, here, as the First Term is 2 and the Ninth Term is 26, we will plug in the values respectively..

a + (n - 1) d

2 + (9 -1) d = 26

2 + 8d = 26

8d = 26 - 2

8d = 24

d = 3

Answer:- The Common Difference is 3
