How many terms are in the arithmetic sequence 9, 2, −5, . . . , −187?
Fantom [35]
9, 2, -5... so is going down by 7 each time, meaning the "common difference" is -7.

\bf n^{th}\textit{ term of an arithmetic sequence}\\\\&#10;a_n=a_1+(n-1)d\qquad &#10;\begin{cases}&#10;n=n^{th}\ term\\&#10;a_1=\textit{first term's value}\\&#10;d=\textit{common difference}\\&#10;----------\\&#10;a_1=9\\&#10;d=-7\\&#10;a_n=-187&#10;\end{cases}&#10;\\\\\\&#10;-187=9+(n-1)(-7)\implies -187=9-7n+7&#10;\\\\\\&#10;7n=9+7+187\implies 7n=203\implies n=\cfrac{203}{7}\implies \boxed{n=29}

PLEASE HELP ASAP 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER
MAVERICK [17]

Answer:

(-2,-5)

Step-by-step explanation:

y = 2x-1

3x-y = -1

We can use substitution

3x - (2x-1) = -1

Distribute the minus sign

3x -2x+1 = -1

x +1 =-1

Subtract 1 from each side

x+1-1 = -1-1

x=-2

Now we need to find y

y = 2x-1

y = 2(-2) -1

y = -4-1

y = -5

(-2,-5)
