Step-by-step explanation:
it is geometric
so we will use this equation:
a(n)=a1*(r)^(n-1)
and we have a(1)=75 , r=15/75=3/15=1/3
explicit formula: a(n)=75*(1/3)^(n-1)
hope this helps
Answer:
2 74/100
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
So we have the expression:

First, evaluate within the absolute value bars. 3 times -4 is -12. Thus:

Now, subtract:

The absolute value of -10 is positive 10. So:

And we're done!
