Answer:
Option D. 5x + 12y + 4z is the corrct one.
This is pretty simple-ish, if you think about it. All we're doing is working backwards.
237,286 + 476 = 237,762
237,762/629 = 378.
We could even check it again, if you want.
378*629 = 237,762
237,762 - 476 = 237, 286.
Therefore, x = 378.
The pattern is formed a geometric sequence
The nth term of the sequence is 
Step-by-step explanation:
The formula of the nth term of a geometric sequence is:
, where
- a is the first term
- r is the common ratio between the consecutive terms
∵ The pattern is 3 , 9 , 27 , 81 , 243
∵ 9 ÷ 3 = 3
∵ 27 ÷ 9 = 3
∵ 81 ÷ 27 = 3
∵ 243 ÷ 81 = 3
- There is a common ratio 3 between each two consecutive terms
∴ The pattern is formed a geometric sequence
∵ The first term is 3
∴ a = 3
∵ The common ratio is 3
∴ r = 3
- To find the nth term substitute a and r in the formula above
∵
∴
- Remember we add the powers of the same base with multiplication
∵ 3 ×
= 
∴ 3 ×
= 
∴ 
∴ The nth term of the sequence is
