The answer is 2,-1 i hope this helps you out!

This statement can be represented as
, since the quotient is the answer to a division problem.
Divide. 
Multiply. 
Simplify. When the numerator and denominator are the same, the fraction is equal to 1. 
Answer:
The explicit formula for the given expression is 2 n - 3
Step-by-step explanation:
Here, the first term of sequence = -1
The common difference = 2
In a ARITHMETIC PROGRESSION:
The nth term of a sequence is given as
a(n) = a + (n-1) d
⇒ Here, a(n) = -1 + (n-1)(2)
= -1 + 2n -2
= 2n - 3
or, a(n) = 2n - 3
Hence, the explicit formula for the given expression is 2n - 3.
Use algebra for such problems
let, Angle COD = x
Angle KOD = y
Angle KPC = z
Given ,. x - y = 61° ( Equation 1 )
x - z = 53° ( Equation 2 )
Subtract 1st equation from 2nd and you'll get :
z - y = 8° ( Equation 3 )
Now since , x + y + z = 180° ( Equation 4 )
Add Equation 3 to Equation 4 and you'll get
x + 2z = 188° ( Equation 5)
From Equation 2 we know that , x -z = 53°
or, x = 53° + z ( Equation 6 )
Put this value of 'x' in Equation 5 and solve for z. you'll get :
(53° + z) + 2z = 188°
or
3z = 188 - 53 = 135°
solving for z we get
z = 45°
put this value of z in Equation 5
x + ( 2 x 45° ) = 188°
or
x = 188° - 90° = 98°
hence , Angle COD = 98°
