Write the first ten terms of a sequence whose first term is -10 and whose common difference is -2.

Since the common difference is -2, then you just have to subtract -2 from everything starting -10. So the answer or the first ten terms of the geometric sequence would be: -10, -8, -6, -4, -2, 0, -2, -4, -6, and -8. If you want to continue, simply subtract negative 2 in every succeeding number.

Ithink it's the first one ( let me know if it right)
