Which of these iterative processes is unstable? (Note: \(\epsilon_n\) is the error in the nth iteration).

\(\frac{\epsilon_{n+1}}{\epsilon_n} = 1\)

\(\frac{\epsilon_{n+1}}{\epsilon_n} = 0.5\)

\(\frac{\epsilon_{n+1}}{\epsilon_n} = 0.75\)

\(\frac{\epsilon_{n+1}}{\epsilon_n} = 1.25\)

\(\frac{\epsilon_{n+1}}{\epsilon_n} = 1\)
