The common difference, d of the arithmetic progression is 2

Step-by-step explanation:

In the sequence 7, 9, 11, we can see that an additional term is gotten upon the addition of 2, so it is an arithmetic progression.

given that that first term a , =7

and the second term a + d = 9

The common difference , d =(a + d) − a

d = 9 − 7

d= 2
