n पदों के लिए, a1, a2, a3, ……., an
गुणोत्तर माध्य = \(\rm ({a_{1}.a_{2}.a_{3}....a_{n}})^{\frac{1}{n}}\)
गणना:
g, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 का गुणोत्तर माध्य है
⇒ g = \((2 × 4 × 8 × 16 × 32 × 64 × 128 × 256 × 512 × 1024)^{\frac{1}{10}}\)
⇒ g = (2 × 22 × 23 × 24 × 25 × 26 × 27 × 28 × 29 × 210\()^{\frac{1}{10}}\)
⇒ g = \(\rm 2^{5.5}\)
⇒ 25 < g < 26
∴ 32 < g < 64 सही है
