A man starts walking east for 5 km, then turns north and walks 3 km, then west for 5 km. How far is he from his starting point? What's your answer?
The man is 3 km away from his starting point.
1. Walking east for 5 km: The man moves 5 km to the east of his starting point. 2. Walking north for 3 km: He then moves 3 km north, maintaining the 5 km distance eastward. 3. Walking west for 5 km: Finally, he moves 5 km west, which cancels out the 5 km eastward movement. At this point, the man is directly 3 km north of his starting point, as the east-west movements cancel out.
The next number is 42
– Differences between consecutive terms:6−2=4 12 - 6 = 6 20−12=8 30−20=10 The differences are increasing by 2 each time: 4,6,8,10 – Next difference:Following the pattern, the next difference should be 12 – 30+12=42 Next term:Add 12 to the last term 30 30+12=42
