5,3,1,-1 find a^18
Arithmetic sequence 5, 3, 1, -1 then value of a^18 is 3814697265625.
Solution:
Given, arithmetic sequence is 5, 3, 1, -1
We have to find the value of
We know that, first term of any A.P is represented by the letter “a”
So, here in our problem first term a = 5
Then we have to find the value of
Hence, the value of a^18 is 3814697265625.
The 18th term of the arithmetic sequence is -29.
An arithmetic sequence is a sequence in which the difference between any term and its preceding term is constant. In this case, the common difference is -2, because each term is decreased by 2 to get the next term. To find the 18th term, we can use the formula:
an = a1 + (n-1)d
where an is the term we want to find, a1 is the first term, n is the position of the term, and d is the common difference.
Using the given sequence, we can substitute the values into the formula:
a18 = 5 + (18-1)(-2) = 5 + 17(-2) = 5 - 34 = -29
Therefore, the 18th term of the given arithmetic sequence is -29.

Answer:
-15.25 feet
Step-by-step explanation:
The reason is that sea level we measure it zero, so above sea level means numbers that are bigger than zero (positive).
In this case, it says that she is scuba diving below sea level, and below sea level number smaller than zero (negatives). There are only two options with negative numbers and they are -14.82 and -15.25. So it has to be one of those two options.
Now, it says that she is more than 15 feet below sea level, to be more than 15 feet means that she is farther than 15 feet of the sea level, it has to be a number that is farther to zero than -15, which is -15.25 feet.
So the answer is -15.25.
