Answer:
Abuja
Yaounde
Kinshasa
Bangui
Kigali
Step-by-step explanation:
The cities on the list are all capitals of countries in Africa. One of these cities is located in Western Africa, three are located in Central Africa, and one is located in Eastern Africa. All of these cities are the most important in their countries, having the biggest economic output and highest levels of development in their respective countries.
The westernmost of them is the city of Abuja, the capital of Nigeria. Cameroon's capital Yaounde comes next, and very close to it, just a little bit more to the east is Kinshasa, the capital of DR Congo. Bangui, the capital of the Central African Republic comes fourth from west to east, though again just a little bit more east than Kinshasa, and Rwanda's capital, Kigali, is clear as the fifth, being clearly the most easter of any of these capitals.
