Mathematics
1 answer:
zzz [600]3 years ago
4 0

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 6(2)^{n-1}

n=1 , plug in 1 for n

6(2)^{1-1}=6

n=2

6(2)^{2-1}=12

n=3

6(2)^{3-1}=24

n=4

6(2)^{4-1}=48

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