Final answer:
The first term of the sequence is -2, the second term is -6, and the common difference is found by subtracting the first term from the second, resulting in a common difference of -4.
Step-by-step explanation:
The sequence given is -2, -6, -10, -14. The first term of the sequence is -2. The second term is -6.
To find the common difference, you subtract the first term from the second term:
Common Difference = second term - first term = -6 - (-2) = -6 + 2 = -4.
Therefore, the common difference for the sequence is -4.
