Find an equation for the nth term of the arithmetic sequence. -17, -14, -11, -8, a. an = -17 + 3(n - 1) b. an = -17 x 3(n - 1) c. an = -17 + 3(n + 1) d. an = -17 + 3(n + 2)

Step-by-step explanation:

Given : Arithmetic sequence : -17, -14, -11, -8, ...

Here the first term ,

Common difference :

The formula to find the nth term is given by :-

i.e.  

Hence, the equation for the nth term of the arithmetic sequence :-

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
