SUMMARY
The series Ʃ (4x+5)^n/2^n converges for values of x within the interval (-7/4, -3/4). The convergence is determined using the ratio test, which states that a series converges if the limit of the ratio of successive terms approaches zero. The correct answer was confirmed by multiple participants in the discussion, affirming the interval as the solution.
PREREQUISITES
