Answer:
d=4
Step-by-step explanation:
subtract the 4th term and the 3rd term (27-23=4), subtract the 3rd term with the 2nd term (23-19=4),
subtract the 2nd term with the 1st term (19-15=4).
as you can see, all their difference was 4, therefore the common difference is 4
27-23=4
23-19=4
19-15=4
if you want to know what the 30th term is you can use the formula dn+c
where d= common difference
n=domain
c= constant
in this problem,
n=30 (because you're finding the 30th term)
c= 11 (you can get the c by subtracting the 1st term with the common difference)
substitute
4(30)+11=131
I answered this because I saw the n=30 so i thought you might need this too
