Find the average of the first 122 even numbers.
प्रथम 122 सम संख्याओं का औसत ज्ञात कीजिए।
Detailed Solution & Logic
Correct Answer:
123
First 122 even numbers: $2,4,6,\dots,244 $
n = 122
Sum of first n even numbers = n(n+1) = \(122 \times 123 = 15006 \)
Average = \(\frac{\text{Sum}}{n} = \frac{15006}{122} = 123 \)
Answer = 123
