పరిష్కారం - జ్యామితీ నిర్ణయాలు

శ్రేణికి సామాన్య రూపాన్ని కనుగొనడానికి, మొదటి పదాన్ని: $$a=3,846$$ మరియు పునరావృత్తి అనుపాతాన్ని: $$r=0.0039001560062402497$$ జామితీయ శ్రేణుల సూత్రానికి ప్లగ్ చేయండి:

$$a_1=3846$$

$$a_2=a_1·r^{n-1}=3846\cdot {0.0039001560062402497}^{2-1}=3846\cdot {0.0039001560062402497}^1=3846\cdot 0.0039001560062402497=15$$
