Answer:
Step-by-step explanation:
The explicit formula for the n-th term of an arithmetic sequence is ...
an = a1 + d(n -1)
where a1 is the first term and d is the common difference.
The sequence of seat counts has a1=5 and d=10, so the explicit formula is ...
an = 5 +10(n -1)
___
The 7th term is ...
a7 = 5 +10(7 -1) = 65
Answer:
9

Answer:
undefined, 13.2
Step-by-step explanation:
got it right.
The three consecutive integers that add up to 450 are 149, 150, and 151.
The consecutive numbers are those numbers that follow each other continuously in the order from smallest to largest numbers.
Given that the sum of three consecutive even numbers is 450
We need to find the 3rd number of the integers.
Now assume the 3 consecutive integers are x, (x+1) and (x+2)
Therefore, x+(x+1)+(x+2)= 450
Combine the like terms;
3x+3= 450
X=149
Thus the second number is 149 + 1 and the third number is 149 + 2.
Hence, the 3rd number of the integers would be 151.

Step-by-step explanation:
Which means that the first number is 149, the second number is 149 + 1 and the third number is 149 + 2. Therefore, three consecutive integers that add up to 450 are 149, 150, and 151. We know our answer is correct because 149 + 150 + 151 equals 450 as displayed above.
