Question 701: An Absolute Geometric Ratio above One Violates the Necessary Term Limit

Original question and givens

Use positive scale=1, exact ratio=6/3>1 and alternating=false. Give (scale, ratio, alternating, absolute_ratio, term_test_obstruction, conclusion).

• G001 — Use positive scale=1, exact ratio=6/3>1 and alternating=false. Give (scale, ratio, alternating, absolute_ratio, term_test_obstruction, conclusion).

Definition and scope

Geometric terms with A>0 and |r|>1 satisfy |a_n|≥A; the terms do not tend to 0, so the series diverges.

• mko-ratio-test-series

Step-by-step derivation

A=1>0; r=2>1; alternating=No

|a_n|=1·(2)^n

|a_(n+1)|/|a_n|=(1·(2)^(n+1))/(1·(2)^n)

absolute ratio=2

r=2>1

|a_n|≥A=1>0 for every n≥0

convergent series ⇒ its terms tend to0

these terms do not tend to0 ⇒ series diverges
