## SmartOwl94 3 years ago HELP ME PLEASE!!!! Identify each sequence as arithmetic or geometric. Then find the common difference or common ratio. 1. 13, 19, 25, 31, ... 2. 16, 24, 36, 54, ... 3. 4, 14, 24, 34, ... 4. 1, 4, 16, 64, ... 5. 35, 33, 31, 29, ... 6. 64, 48, 36, 27, ...

1. arithmetic - c d = =6 2, geometric c r = 24/16 = 1.5 3. arithmetc c d = 10 4. geometric c r = 4 do you follow the reasoning can you finish this off?

3. creative_huh

6 looks tough

4. SmartOwl94

umm yeah I think I get it, so you are subtracting 2 to get each successive term in number 5

5. joeywhite

6 is a G eometric

6. SmartOwl94

but how do u know its geometric?

7. shivam_bhalla

For 6th one Divide 2nd term by 1st term. You will get c.r = 3/4

8. joeywhite

yes so no 5 has a common difference

9. joeywhite

shivam has it
