Which sequence represents an arithmetic sequence? −5, −7, −10, −14, −19, … 1.5, −1.5, 1.5, −1.5, … 4.1, 5.1, 6.2, 7.2, … −1.5, −1, −0.5, 0, …

we know that

arithematic sequence will always have common difference

(a)

−5, −7, −10, −14, −19, …

we can see that

they are not equal

so, this is not arithematic sequence

(2)

1.5, −1.5, 1.5, −1.5, …

we can see that

they are not equal

so, this is not arithematic sequence

(3)

4.1, 5.1, 6.2, 7.2, …

we can see that

they are not equal

so, this is not arithematic sequence

(4)

−1.5, −1, −0.5, 0, …

we can see that

they are equal

so, this is arithematic sequence
