Responses

f(n)=240(120)n−1
f left parenthesis n right parenthesis equals 240 left parenthesis 120 right parenthesis superscript n minus 1 baseline

f(n)=240+(n−1)12
f left parenthesis n right parenthesis equals 240 plus left parenthesis n minus 1 right parenthesis Start Fraction 1 over 2 End Fraction

f(n)=240(32)n−1
f left parenthesis n right parenthesis equals 240 left parenthesis Start Fraction 3 over 2 End Fraction right parenthesis superscript n minus 1 baseline

f(n)=240(12)n−1
