In 2-3 sentences describe why the only way an infinite geometric series has a sum is if |r| < 1.
alisha [4.7K]

Answer:


Step-by-step explanation:

A geometric series is one where each term is multiplied by a constant value known as r to get the next term

Sum of n terms of a geometric series is

\frac{a(r^n-1}{r-1},|r|>1\\\frac{1-r^2}{1-r},|r|

Sum of infinite series is obtained as the limiting value of this sum when n tends to infinity

We find that only when |r|<1, r power n tends to 0 as n tends to infinity.

Other r power n diverges.

Hence geometric series infinite sum formula is valid only when

|r|<1 since the series sum converges to a finite value

Log1/2 28? What is it?
I am Lyosha [343]
\log_a(b\cdot c)=\log_ab+\log_ac\\\\\log_ab^c=c\cdot\log_ab\\\\\log_aa=1\\--------------------\\\log_\frac{1}{2}28=\log_\frac{1}{2}(4\cdot7)=\log_\frac{1}{2}4+\log_\frac{1}{2}7=\log_\frac{1}{2}2^2+\log_\frac{1}{2}7\\\\=2\log_\frac{1}{2}2+\log_\frac{1}{2}7=\boxed{2+\log_\frac{1}{2}7}


\log_ab=\frac{\log_cb}{\log_ca}\\-------------------------\\\log_\frac{1}{2}7=\frac{\log\frac{1}{2}}{\log7}\approx\frac{-0.6931}{1.9459}\approx-0.3562\\\\therefore\\\\\boxed{\log_\frac{1}{2}28\approx2+(-0.3562)=1.6438}
