Answer:
Step-by-step explanation:
Since there's no one one number you can add to one number in the sequence to get to the next number, this is not arithmetic. It must be geometric. We need then to find the common ratio. Let's start with the first 2 numbers, find a ratio, and then use it to test for accuracy.
10x = 15 and
x = 
If this is in fact a geometric sequence witha common ratio of 3/2, we should be able to multiply 15 by 3/2 to get to the next number in the sequence. Let's try it out:
Good. So the common ratio is 3/2. The formula for an explicit geometric formula is
where a1 is the first number in the sequence and r is the common ratio. Filling in:

The sampling technique used when A scientist chooses twenty people at random from each class is stratified sampling.
<h3>What is
stratified sampling?</h3>
Stratified sampling can be described as the type of sampling method whereby the total population is been divided into smaller groups or strata.
This usually done to complete the sampling process, hence The sampling technique used when A scientist chooses twenty people at random from each class is stratified sampling.
