Subject and Verb do not agree. Sequoia and Charles plan to exercise together.
The subject of this sentence is a compound subject (Sequoia and Charles). A compound subject is a plural subject because it has more than one. The verb "plans" agrees with a singular subject because it ends with /s/. In order to make the subject and verb agree, the /s/ at the end of "plans" needs to be eliminated. The revised sentence should be "Sequoia and Charles plan to exercise together."
ethos appeals to validity (proves you are credible), logos appeals to logic and pathos appeals to emotion. All 3 of these rhetorical devices are necessary to write an effective persuasive essay.
