The recursive rule for a geometric sequence is given.
2 answers:
Answer:
an = 2/5 * (5) ^ (n-1)
Step-by-step explanation:
The common ratio is 5
(That is the number we multiply by)
The formula is
an = a1 (r) ^ (n-1)
an = 2/5 * (5) ^ (n-1)
Answer:

Step-by-step explanation:
The recursive rule for a geometric sequence is given.
a1= 2/5; an= 
a1 is the first term = 2/5
USe the recirsive rule. compare an=
, where 'r' is the common ratio with the given recursive formula
r= 5, common ratio is 5
General explicit rule

a1=2/5 and r= 5
So explicit rule becomes

Answer:
2a +b =5
Step-by-step explanation:
4a + 2b = 10
Divide each side by 2
4a/2 +2b/2 = 10/2
2a +b =5
