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:

Step-by-step explanation:
Umm kid u forgot to put in like -, +, or x, or at least /
but here are the answers, if its addition the answer is 1/4, if its subtraction answer is -19/4 but if u simplify it to mixed fraction answer would be -4 3/4, if its multiplication answer would be -45/8 but simplify that and it would be -5 5/8, if its division answer would be -9/10 hope this helps
