Find a formula for the nth term of the arithmetic sequence.
First term 10
Common difference -3
an = [? ]n + [ ]

Given:

The first term of an arithmetic sequence = 10

Common difference = -3

To find:

The formula for nth term of the arithmetic sequence.

Solution:

The nth term of an arithmetic sequence is:

Where, a is the first term and d is the common difference.

Putting and in the above formula, we get
