Answer:

90

Step-by-step explanation:

To find s4  we find sum of values when n=1,n=2,n=3,n=4

given expression is [tex]6(2)^{n-1}[/tex]

n=1 , plug in 1 for n

[tex]6(2)^{1-1}=6[/tex]

n=2

[tex]6(2)^{2-1}=12[/tex]

n=3

[tex]6(2)^{3-1}=24[/tex]

n=4

[tex]6(2)^{4-1}=48[/tex]

Sum of all 4 terms = 6+12+24+48=90
