The greatest common factor for 48 and 60 is:
12
Answer:

Step-by-step explanation:
a1 = 8
a9 = 56
Using formula for finding nth term of arithmeric sequence

We have to find 24th term, therefore n = 24
is the first term but we are missing d
d is the difference between the two consecutive terms, lets calculate it first
a9 = 56
Using the above given formula for finding d
put n = 9, a9= 56

56 = 8 + 8d
8d = 48
d = 6
Getting back to main part of finding 24th term
n = 24, d = 6, a1 = 8
put values in nth term formula
