Help me with this question.

The equation for the nth term of the arithmetic sequence is:

The is 140

Step-by-step explanation:

"a" represents the first term which is -5.

"d" represents the common difference which is 5.

To find the common difference, just subtract the 2nd and 1st term.

0 - (-5) = 5

Now put the values in the equation:

We are finding the 30th term so just put 30 to the "n" to help us find the 30th term of the sequence.

So the 30th term is 140

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
