3x=9
x=3
Answer:
see explanation
Step-by-step explanation:
Note the common ratio r between consecutive terms of the sequence
r = 6 ÷ 3 = 12 ÷ 6 = 24 ÷ 12 = 48 ÷ 24 = 2
The explicit rule for a geometric sequence is
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 3 and r = 2, thus
= 3
← explicit rule
