To determine which sequence is an arithmetic sequence, we need to check if the difference between consecutive terms is constant.

For 250,370,490,620,730:

Difference between 370 and 250: 370 − 250 = 120

Difference between 490 and 370: 490 − 370 = 120

Difference between 620 and 490: 620 − 490 = 130

Difference between 730 and 620: 730 − 620 = 110

The differences are not consistent, so this is not an arithmetic sequence.

For 150,250,370,490,620:

Difference between 250 and 150: 250 − 150 = 100

Difference between 370 and 250: 370 − 250 = 120

Difference between 490 and 370: 490 − 370 = 120

Difference between 620 and 490: 620 − 490 = 130

The differences are not consistent, so this is not an arithmetic sequence.<...
