Question

What is the nth term for the sequence 25,20,15,10,5
Please and thank you in advance

Answer 1

Answer:

5n

Step-by-step explanation:

Arrange the sequence in ascending order,

5,10,15,20,25,

First term a = 5

Difference d = 5

by Arithmetic progression, Tn = a+(n-1)d

Tn = 5 +(n-1)5

Tn = 5 +5n -5

Tn = 5n
