Answer:
= - 1
Step-by-step explanation:
The explicit formula for a geometric sequence is
= a
where a is the first term and r the common ratio
Here a = - 1 and r = 3 ÷ - 1 = - 3 , thus explicit formula is
Answer: 6
The factors of 6 are 1,2,3 and 6
49/12
Just mulitply the top and the bottom across.
7*7/4*3
