Answer: 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
