Which set of numbers is an arithmetic sequence? 1, 5, 8, 13, , 4, 8, 32, , 21, 17, 13, , 27, 9, 3,

The correct option is 3.

Step-by-step explanation:

The sequence is called an arithmetic sequence if the difference between every two consecutive terms are same.

In sequence 1, 5, 8, 13, ...

Since , therefore the sequence 1, 5, 8, 13, ... is not an arithmetic sequence.

In sequence 2, 4, 8, 32,...

Since , therefore the sequence 2, 4, 8, 32,... is not an arithmetic sequence.

In sequence 25, 21, 17, 13, ...

Since this sequence has common difference of -4 therefore the sequence 25, 21, 17, 13, ... is an arithmetic sequence.

In sequence 81, 27, 9, 3, ...

Since , therefore the sequence 81, 27, 9, 3, ... is not an arithmetic sequence.

Hence the correct option is 3.

(-1,0) and (4,0) are x-intercepts.

step-by-step explanation:

x-intercepts are all points on the x-axis.

points (-1,0) and (4,0) are both x -intercepts.

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
