Answer:
Choice A:
Step-by-step explanation:
means we looking for first term 5 and the sequence is going up by 2.
In general,
means you have first term and the sequence has a common difference of d.
So it is between the first two choices.
The explicit form of an arithmetic sequence is:
An equivalent recursive form is
So d again here is 2.
So choice a is correct.
Mean = 450 sec
standard deviation = 50 sec
450-50 =400
450+50=500
Between 400 sec and 500 sec means one deviation above and one deviation below the mean, and it is 68%.
68%=0.68
0.68*288= 195.84≈196
Answer is d) 196
