Focus target in cast sequence

Hi guys, been a lurker for a long time and this is my first post.

Not sure if this is in the right spot but i have a macro

/castsequence Rake, Sunfire, Moonfire, Swipe, Swipe, Swipe, Swipe, Rip, Sunfire, Moonfire, Swipe, Rake, Swipe, Swipe, Swipe, Lifebloom, Ferocious Bite

Near the end i have a lifebloom that i would want to cast on my focus target rather than myself.

I have tried various different commands but have been unsuccessful in all of them. I wondered if anyone could help me?
