Answer:
Arithmetic sequence
for
Step-by-step explanation:
We are given that a sequence
We have to identify the sequence as arithmetic or geometric and write an explicit formula .
When the difference of consecutive terms is constant then the sequence is an arithmetic.
Hence, the sequence is an arithmetic.
for
The probability of three independent events happening one after the other is the multiplication of the probability of the single events.
The probability of spinning an odd number is 5/10=1/2, because there are 5 odd numbers (1,3,5,7 and 9) out of the 10 numbers from 1 to 10.
The probability of spinning a number less than 4 is 3/10, because there are 3 numbers (1,2 and 3) that are less than 4 out of the 10 numbers from 1 to 10.
The probability of spinning a 7 is 1/10, because you only have one good outcome out of 10.
So, the probability of winning the game is
