Question

Can someone help me with this math homework please!

Answer 1

Answer:

Option 3 and 5

Step-by-step explanation:

- 5, 5, - 5, 5, - 5, .....

5 - ( - 5 )

= 5 + 5

= 10

- 5 - 5

= - 10

Here, common difference is not same, so this sequence is not an A.P

96, 48, 24, 12, 6

48 - 96 = - 48

24 - 48 = - 24

Here, common difference is not same, so this sequence is not an A.P

18, 5.5, - 7, - 19.5, - 32, .....

5.5 - 18 = - 12.5

- 7 - 5.5 = - 12.5

Here, common difference is same, so this sequence is an A.P

- 1, 3, - 9, - 27, - 81, .....

- 3 - 1 = - 4

- 3 - 9 = - 12

Here, common difference is not same, so this sequence is not an A.P

16, 32, 48, 64, 80, .....

32 - 16 = 16

48 - 32 = 16

Here, common difference is same, so this sequence is an A.P
