SUM #3: sum{k=1,4} 2k = 2XL_0 = 2_0 Is this right?

Is this right?

Yes. Why do you doubt it?

Hello Barbra. In the future, please use different subject lines when starting new threads. You have three threads all titled, "SUM". Using the same name for everything makes it difficult for tutors to differentiate between conversations, especially when viewing board indices or search results.

I'll change the current names to SUM #1, SUM #2 and SUM #3, based on timestamps.

Thank you! ?
