Write the related series for the finite sequence –7, –10, –13, . . ., –22. then find the sum.–7 + (–10) + (–13) + (–16) + (–19) + (–22) = –87 –7 + (–10) + (–13) + (–15) + (–18) + (–22) = –85 –7 + (–10) + (–13) + (–14) + (–18) + (–22) = –84 –7 + (–10) + (–13) + (–17) + (–20) + (–22) = –89
Accepted Solution
A:
I would say the last one, -7+(-10)+(-13)+(-17)+(-20)+(-22)=-89 , it seems the most reasonable since you go up by -3, hope this is correct and helps if not i apologize
