Question

Write an arithmetic sequence with common difference -5. 

Step-by-Step Solution

Answer

An arithmetic sequence with common difference -5 is 20, 15, 10, 5 …..

Step 1. Given Information.

Given the common difference of an arithmetic sequence is -5.

Step 2. Calculation .

Let the first term be  $a_1=20$

The common difference is  $d=-5$

 

So,

The second term of the arithmetic sequence is $20-5=15$ 

The third term of the arithmetic sequence is  $15-5=10$

The fourth term of the arithmetic sequence is  $10-5=5$

Step 3. Conclusion .

Hence, the arithmetic sequence with common difference -5 is 20, 15, 10, 5, ….
