Answer:
Below in bold.
Step-by-step explanation:
Nth term an = a1 + d(n - 1) where a1 = term 1 and d = common difference.
Here a1 = 5 and d = 8-5 = 3.
So an = 5 + 3(n - 1)
15th term a15
= 5 + 3(15 - 1)
= 5 + 42
= 47.
5/7 = x/42
5/1 = x/6
X = 30
4/3
40/30
60/45
Simply multiply or divide both the 20 and the 15 to get an equivalent ratio.
