Question

. Determine whether each sequence is arithmetic or not. If it is, find the common difference and give the next two
terms.
1. 7, 10, 13, 16, ...
2. -6, 4, 2, 0,...
3. 1/3, 2/3, 1, .
4. 3, 5, 8, 12, 17, ...
5. 2, 1, 1/2,1/4,...​

Answer 1

Answer:

1. common difference is 3 and next two terms is 19 and 22

2. this sequence is not arithmetic

3. the common difference is 1/3 and next two terms is 4/3 and 5/3

4.the next two terms is 23 and 30. the difference between 2 numbers is increasing by 1 each time

5. the next 2 terms are 1/8 and 1/16. each number is getting divided by 2 as we progress further
