<span> 32=2^5
^ = "to the power of"
1/32=1/2^5
1/2^5=2^-5
so
1/32=2^-5 </span>
The rule of geometric sequence is ⇒⇒⇒ a * r^(n-1)
Where a is the first term and r is the common ratio
for the given sequence √5 , √10 , 2√5 , .......
a = √5
r = √10 / √5 = √2
The ninth term = √5 * (√2)^(9-1) = √5 * (√2)⁸ = 16 √5
the correct answer is the third option 16√5
4/6 numbers are greater than 2
1/2 chance of flipping heads
Multiply the two fractions together to get the probability
1/2*4/6=2/6=1/3
1/3 probability
