Answer:
a(n)= a(n-1) .10
Clearly see the equation
you can do it directly Apply logic
Every n th term is 10 times of previous n-1 th term
That is common ratio an/a(n-1)= 10
So, We have to find 4 th term
So, 4 th term is simply
1st term × (common ratio)^(4-1)
-11( 10)^3
-11000
Thanks
We add up all those numbers (excluding 30) and divide by the number of numbers (9). This results in 78.8 (round up to 79).
79-74 = 5. So the mean has increased by 5 points. (C)
