Any fraction with a denominator of 8 and
a numerator less than 6.66 does the job.
Answer:
20x6
Step-by-step explanation:
20x (x stands for multiply/times)
6(sum/add 4+2)
20x6
Hope this helps.
They are equivalent because 4:5 can both be multiplied by 2 making 8:10.
Answer:
Step-by-step explanation:instead, try making the subscripts and superscripts stand out:
n-1
a = a * r
n n-1
Believe me, it's worth the extra work to do this!!
Given the sequence -3, -6, -12, -24, you can easily see that the first term,
a is -3. The common factor is 2. Note how (-3)*2=-6, and so on.

So, a = -3 and r=2.

So the formula for this geometric sequence is
n-1
a = -3*2
n
