Arithmetic sequence
5,3,1,-1 find a^18
Answers
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.
Final answer:
The 18th term of the arithmetic sequence is -29.
Explanation:
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.

The number of times Jana will roll a 2 will be 13.
What is Probability?
Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Jana has a number cube numbered 1 to 6.
When Jana rolls the number cube 1 time, there is an equal chance of getting each number.
Probability that the number is 2 = 1/6
So, there is a 1/6 probability that the number rolled is 2.
Jana plans to roll the cube 78 times.
So the number of times Jana will roll a 2 = 78 × (1/ 6) = 13
Hence the number of times that Jana will roll a 2 in the number cube is predicted as 13.
