f(n)=56×(−12)n−1
f of n is equal to 56 times open paren negative 1 half close paren raised to the n minus 1 power
f(n)=12×(56)n−1
f of n is equal to 1 half times 56 raised to the n minus 1 power
f(n)=(−12)×56n−1
f of n is equal to open paren negative 1 half close paren times 56 raised to the n minus 1 power
f(n)=56×(12)n−1
f(n)=56×(−12)n−1
f of n is equal to 56 times open paren negative 1 half close paren raised to the n minus 1 power
