The sum of an Arithmetic Series is given as:
where,
d = Common Difference = Difference of any two consecutive terms.
So,
d = 8
a1 = First term = 1
Using the values, we get:
The above equation gives the formula for n terms of an Arithmetic Series.
So, option A is the correct answer
Answer:
252
Step-by-step explanation:
t50 = t1 + (n - 1)(d)
= 7 + (50 - 1) (5)
= 7 + (49)(5)
= 7 + 245
= 252

The function that correctly returns grades from 60 percent to a 100 percent is f(x) = [[(x - 50)/10]]
<h3>How to determine this function</h3>
The question tells us that the students do not fail and they do not get a 100 percent score either.
Hence there is no need for worry if the grade is at 5.0 or less than 1.
For example we have
x = 82.976
f(82.976) =[[(82.976-50)/10]
This would then be 3.29
This is then = 3.0
This function is not an odd function and it is not an even function. This is because the domain does not have negative values.
