Final answer:
The number pattern is [0.57, 0.66, 0.75, 0.84, ...]. The rule to describe the pattern is to add 0.09 to the previous term to obtain the next term.
Step-by-step explanation:
The number pattern given is [0.57, 0.66, 0.75, 0.84, ...].
Looking at the pattern, we can observe that the first term is 0.57. To get the second term, we add 0.09 to the previous term, giving us 0.66. Similarly, to get the third term, we add 0.09 to the previous term, resulting in 0.75. This pattern continues, with each term increasing by 0.09.
So, the 3 terms in the number pattern are 0.57, 0.66, and 0.75, and the rule to describe the pattern is to add 0.09 to the previous term to obtain the next term.
