What is the 50th term of the arithmetic sequence 3, 7, 11, 15, ? a. 151 b. 199 c. 203 d. 53

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:

where

a is first term of sequence

n is term position

d is common difference

= 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

⇒

⇒

⇒

⇒

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

So, OPTION B is correct .

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
