XXII. Let the 1st consecutive even member = 2x

Therefore, the 2nd consecutive even member = 2x + 2

The 3rd consecutive even member = 2x + 4

The 4th consecutive even member = 2x + 6

The 5th consecutive even member = 2x + 8

According to the problem,

2x + (2x + 2) + (2x + 4) + (2x + 6) + (2x + 8) = 4520

⟹ 10x + 20 = 4520

⟹ 10x = 4520 - 20

⟹ 10x = 4500

⟹ x = 4500/10

⟹ x = 450

Therefore, 1st consecutive even member = 2x = 2 × 450 = 900

The 2nd consecutive even member = 2x + 2 = 2 × 450 + 2 = 902

The 3rd consecutive even member = 2x + 4 = 2 × 450 + 4 = 904

The 4th consecutive even member = 2x + 6 = 2 × 450 + 6 = 906

The 5th consecutive even member = 2x + 8 = 2 × 450 + 2 = 908

Therefore, the numbers are 900, 902, 904, 906 and 908.
