Write a rule for a geometric sequence that has -6 as its first term and a common ratio of 2. What is the tenth term of this sequ
slega [8]
The general form of the geometric sequence is a_{n} = a_{1} (r) ^{n-1}, where a sub n is the number term you're looking for (we're looking for the tenth term). a sub 1 is the first term in the sequence (ours is -6), r is the common ratio, and n-1 is the numbered term you're looking for minus 1.  Our formula then looks like this: a_{10} =-6(2) ^{10-1}.  Simplify it to  a_{10} =-6(2)^9.  Take 2 to the 9th power then multiply it by -6 to get -3072.  C is your answer.

What are the chances of flipping a coin 12 times and it landing on heads 11 times?
lubasha [3.4K]
12 flips, 11 heads, 1 tails
Let's say there's a 50-50 chance of landing heads.
There are 12 flips and 12 specific outcomes.
The probability is 2^(-12) = 1/4096 = 0.0244%

If the last flip doesn't matter, then the probability would be 2^(-11) = 1/2048 = 0.0488%.

Have an awesome day! :)
