Step-by-step explanation:
That's why, in 2015, the NFL decided to make extra points more difficult, moving them 13 yards back. Since then, the success rate has hovered between 93 percent and 95 percent. Until Sunday, when that ugly day for kickers dropped the success rate below 93 percent on the season.
Answer:
0
Step-by-step explanation:
x = 2
2 x 3 = 6 + 5 = 11
2 - 2 = 0
What is the question exactly?
Answer:
= 1+2n and 63
Step-by-step explanation:
the question belongs to arithmetic sequence and
can be determined by the formula
= a1 + d (n-1)
Let "
" represents the number of band members in the nth row
and 'd' represents the common difference.( as stated each row has 2 more band members than the row before it)
therefore, d=2
'a1' represents first row that has three members. So, a1 = 3
->Rule for nth term will be:
= 3 + 2(n-1)
= 3 + 2n -2
= 1+2n
-> In order to find total number of band members '
'
Let
represent total number in n rows
We'll use the formula, i.e
= n/1 (
+
)
where, n is the number of terms,
is the first term and
is the last term
So,
n=7
= 1 + 2(7)= 15
=>
= 7/2 (3 + 15)
= 63
The total number of band members are 63
