Answer:
Answer: a5 = 2500
Step-by-step explanation:
For a geometric sequence:
First term = a0
Second term = a1 = a0*r
Third term = a2 = a0*r^2
Fourth term = a3 = a0*r^3
....
nth term = a(n-1) = a0*r^(n-1)
Given: a1 = 4 = a0*r
Also: r = 5
So, a0*5 = 4 => a0 = (4/5)
a5 = a(6-1) = Sixth term = a0*r^5 = (4/5)*5^5 = 2500
Hope this helps

Hello there! :)
Answer:
1. 
2. 
Step-by-step explanation:
1. 3/5+4/15
First, you multiply by numerator and denominator.
3*3=9
5*3=15

Then, you had to combine by the fractions.

Add by the numbers from left to right.
9+4=13
<u><em>13/15 is the final answer.</em></u>
______________________________________________
2. 5/6-1/4
First, you multiply by 2 both sides of numerator and denominator.
5*2=10
6*2=12
10/12
3/12

Subtract by the numerator.
10-3=7
<em><u>7/12 is the final answer.</u></em>
