पहिल्या 120 विषम नैसर्गिक संख्या.
वापरलेले सूत्र:
n विषम नैसर्गिक संख्यांची सरासरी = (n विषम संख्यांची बेरीज) / n
पहिल्या n विषम नैसर्गिक संख्यांची बेरीज = n2
गणना:
येथे, n = 120
पहिल्या 120 विषम नैसर्गिक संख्यांची बेरीज = 1202
⇒ बेरीज = 120 × 120 = 14400
सरासरी = बेरीज / n
⇒ सरासरी = 14400 / 120
⇒ सरासरी = 120
पहिल्या 120 विषम नैसर्गिक संख्यांची सरासरी 120 आहे.
