Write down in terms of n, an expression for the nth term of the following sequences:
a) 12 10 8 6 4
b) 25 20 15 10 5

In bold below.

Step-by-step explanation:

a) 12 10 8 6 4

This is an arithmetic sequence with common difference -2.

nth term = a1 + (n - 1)d

= 12 + (n - 1)-2

= 12  -2n + 2

= -2n + 14.

b) 25 20 15 10 5

This is an arithmetic sequence with common difference -5.

nth term = a1 + (n - 1)d

= 25 + (n - 1)-5

= 25  - 5n + 5

= -5n + 30.
