Question

state weather the sequence -6,-1,4,9 is an AP or not​

Answer 1

Answer:

yes it is an AP as common difference is 5.

Step-by-step explanation:

-1-(-6)=5

4-(-1)=5

9-4=5

Answer 2

to check whether a sequence is an AP or not, we find the common difference between successive terms, if common difference is same, we conclude that the given sequence is an AP.

in this case,

-1-(-6) = 5

4-(-1) = 5

9-4 = 5

since the common difference is same, we conclude that the given sequence is an AP
