A seemingly simple question on the "Road to Olympia" competition knocked out four contestants.

The question seemed simple, but it stumped all four contestants in the "Road to Olympia" program.

A 30-point math question from the "Road to Olympia" competition once became the focus of debate on social media. The question was as follows: "An did 119 pull-ups in 7 days. Each day he increased the number of pull-ups by 4 compared to the previous day. How many pull-ups did An do on the first day?"

After 20 seconds of thinking, contestant Van Son ( from Thanh Hoa ) gave the answer "10" and did not score any points. Then, the opportunity was given to the remaining 3 contestants, but none of them pressed the buzzer to answer.
