-4, 8, – 16, 32, ... represents a geometric sequence.
Which equation below is an explicit formula that represents the sequence? Pick one
1) f(n) = -4(2)-1
2) f(n) = -4(-2)n-1
3) f(n) = 2(-4)n-1
4) f(n) = –2(-4)n-1

Can someone plz me understand how to do these. plz, show work.in exercises 1-4, rewrite the expression in rational exponent form.[tex]\sqrt[4]{625} \sqrt[3]{512} (\sqrt[5]{4} )³ (\sqrt[4]{15} )^{7}\\ (\sqrt[3]{27} )^{2}[/tex]

Can someone me and explain..will award brainlest!
