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.
That’s easy. He just has to score lower than the lowest athlete’s time. Since the lowest time is 9.75 seconds, any time lower than that will win him the competition.
Answer:
7,7,12.5
Step-by-step explanation:
since we know that 2 sides are equal,
4x+1=5x-0.5
5x-4x=1+0.5
x = 1.5
sub x = 1.5 into the different eqns
4(1.5)+1 = 7
5(1.5)-0.5 = 7
9(1.5)-1 = 12.5
