Answer:
Jimmy has a ratio of 1:20, or 1 page:20 seconds. Carlo has a ratio of 1:30, or 1 page:30 seconds. Jimmy reads at a faster pace than Carlo, as he is able to read a page in 2/3 of the time it takes Carlo.
Step-by-step explanation:
Jimmy reads a page, on average, every 20 seconds.
5 × 60 = 300
300/15 = 20
therefore, one page every 20 seconds
1:20
Carlo reads a page, on average, every 30 seconds.
6 × 60 = 360
360/12 = 30
therefore, one page every 30 seconds
1:30
Answer:
Step-by-step explanation:
Given is the sequence 3, 8, 13, 18, 23, ….:
We find that this is a geometric sequence with each term added with 5 to the previous term
Hence recursive formula is 
Non recursive formula:

iii) Start with 3.
Add 5 and write as 2nd term
Take the resulting term and add 5 and mark as 3rd term
Repeat this m times.
