Answer

\(\boxed{\text{City E}}\) will have the largest population in 5 years.

Steps

Step 1 ：Calculate the population of each city in 5 years: City A: \(1000 + 5 \times 50 = 1250\)

Step 2 ：City B: \(2000 + 5 \times 100 = 2500\)

Step 3 ：City C: \(3000 + 5 \times 150 = 3750\)

Step 4 ：City D: \(4000 + 5 \times 200 = 5000\)

Step 5 ：City E: \(5000 + 5 \times 250 = 6250\)

Step 6 ：Compare the populations: \(1250 < 2500 < 3750 < 5000 < 6250\)

Step 7 ：\(\boxed{\text{City E}}\) will have the largest population in 5 years.
