Answer:
(30-5n)
Step-by-step explanation:
The given sequence is :
25,20,15,10,5
Here,
First term, a = 25
Common difference = 20-25 = -5
We need to find the nth term of the given sequence. The formula for the nth term is given by :
[tex]a_n=a+(n-1)d\\\\a_n=25+(n-1)(-5)\\\\=25-5n+5\\\\=30-5n[/tex]
So, the nth term of the above sequence is (30-5n).
