Question

13] The Geometric Progression between -4 and -9​

Answer 1

Answer:

Formula for Geometric Progression

$G_{p}$ $= [a * r^{(n-1)}]$

$a - first \: \: term \: \:in \: \:the \: \:series,\\n - last \:\:term \:\: in \: \:the \:\: series,\\r - common \: \:difference.$

$Here,$

$a = -4\\n = -9\\r = (-4) - (-9) = -13$

$So,\\Geometric \:Progression = -1.7484969e-13$
