ఉపయోగించిన కాన్సెప్ట్:
ఈ రకమైన ప్రశ్నలో, ఇక్కడ ‘r’> 1, అప్పుడు G.P యొక్క n పదాల మొత్తం = Sn \( = \frac{{a\left( {{r^n} - 1} \right)}}{{r - 1}}\)
ఉపయోగించిన సూత్రం:
\({S_n} = \frac{{a\left( {{r^n} - 1} \right)}}{{r - 1}}\)
n = 10
సాధన:
ఇచ్చిన సిరీస్ను పరిశీలిస్తే
16, 32, 64, 128, ......
\({S_{10}} = \frac{{16\left( {{2^{10}} - 1} \right)}}{{2 - 1}}\)
⇒ S10 = 16 × 1023 = 16368
∴ ఇచ్చిన సిరీస్ యొక్క మొదటి 10 సంఖ్యల మొత్తం 16368Last updated on Jun 2, 2025
