Just set each expression equal to 3(n+6). If you get the same answer on both sides (x=x) then that expression is equivalent! :)

Answer:

n=-6

Step-by-step explanation:

Equate the equation to zero

3(n+6)=0

Open the bracket

3n+18=0

Substrate 18 from both sides

3n=-18

Divide both sides by 3

n=-6

Therefore the answer to that given equation is -6

What is the 50th term of the arithmetic sequence 3, 7, 11, 15, ... ?
zysi [14]

Answer:

B. 199

Step-by-step explanation:

We are given an Arithmetic sequence : 3, 7, 11, 15, ...

We are supposed to find the 50th term .

So, first consider the formula of nth term in Arithmetic mean:

a_{n} = a+(n-1)*d

where

a is first term of sequence

n is term position

d is common difference

a_{n}= the term you are supposed to find

Now,

a = 3 ( first term )

n = 50 th term ( given )

d = 7-3 = 11-7 = 4(common difference

Substitute these value in the formula given above

⇒a_{50} = 3+(50-1)*4

⇒a_{50} = 3+(49)*4

⇒a_{50} = 3+196

⇒a_{50} = 199

Hence ,The 50th term of given arithmetic sequence is 199

So, OPTION B is correct .
