4.16 because that is what I got in the answer
Answer:
a4 = 189
Step-by-step explanation:
Geometric sequence:
In a geometric sequence, the quotient r between consecutive terms is always the same.
The nth term of the sequence is given by:
In which 
is the first term.
In this question:
The fourth term is:
So
a4 = 189
Step 2 is wrong: 4x - x = 5x
X = -11 is the actual answer, pretty sure.
Hope this helps and please mark as brainliest. If you have any other doubts, feel free to ask.
Given,
The carrot comes in pack of 80
Zunchie comes in the pack of 40
The paper comes in the pack of 50.
To find,
The fewest number of each kind of seed that farmer brown will buy.
Solution,
To find least no of each kind, we must take the LCM of the above numbers such that,
The prime factors of the given numbers are :
80 = 2 × 2 × 2 × 2 × 5
40 = 2 × 2 × 2 × 5
50 = 2 × 5 × 5
LCM of 80,40 and 50 = 2 × 2 × 2 × 2 × 5 × 5
= 400
He should buy,
400/80 = 5 carrot seeds
400/40 = 10 zunchie seeds
400/50 = 8 papper seeds.
Answer:
the first one is 0.2222222222... the second is 0.14
