If a national event is held every 3 years and the last event was in 2019, how many events will occur by the end of 2030? (2022)

If a national event is held every 3 years and the last event was in 2019, how many events will occur by the end of 2030? (2022)

Step 1: Identify the year of the last event, which is 2019.
Step 2: Determine the frequency of the events, which is every 3 years.
Step 3: Calculate the next event after 2019 by adding 3 years: 2019 + 3 = 2022.
Step 4: Calculate the next event after 2022 by adding 3 years: 2022 + 3 = 2025.
Step 5: Calculate the next event after 2025 by adding 3 years: 2025 + 3 = 2028.
Step 6: Check if there will be another event before the end of 2030. The next event would be 2028 + 3 = 2031, which is after 2030.
Step 7: List all the events that occurred by the end of 2030: 2019, 2022, 2025, and 2028.
Step 8: Count the total number of events: 4 events.
