Answer:
1.25
Step-by-step explanation:
a = 10 and r = 0.5
The formula for calculating any term in a geometric sequence is a (the first term) times r (the common ratio) raised to the power of n - 1.
In this case n = 4, since we're looking for the fourth term.
so,
Un = ar^n-1
= ar^4-1
= ar^3
U4 = 10 × 0.5^3
= 10 × 0.125
= 1.25

Answer:
3:9
Step-by-step explanation:
First, we need to put the numbers in order
12,15,15,18,20,29,33,42
the median is the middle number...
notice that have an even number of numbers...u have 8 numbers....when u have an even number of numbers, to find the median, take the 2 middle numbers and divide by 2.
median = (18 + 20) / 2 = 38/2 = 19
** if u would have had an odd number of numbers, then u will only have one middle number and that would be ur median
