What is the fifth term of the sequence
{2n - 1 / n}?
a)4,
b)14/5
c)7/4
d)9/5
assuming the first term is 1, and there is no good reason it should be, then
1,3/2, 5/3, 7/4, ...
To find the fifth term of the sequence {2n - 1 / n}, we can start by substituting the values of 'n' and simplifying the expression.
The given sequence is {2n - 1 / n}, where the first term is 1.
Let's substitute 'n' with the values to find the terms of the sequence:
For the first term (n = 1):
2(1) - 1 / (1) = 1/1 = 1
For the second term (n = 2):
2(2) - 1 / (2) = 3/2
For the third term (n = 3):
2(3) - 1 / (3) = 5/3
For the fourth term (n = 4):
2(4) - 1 / (4) = 7/4
For the fifth term (n = 5):
2(5) - 1 / (5) = 9/5
Therefore, the fifth term of the sequence {2n - 1 / n} is 9/5.
Hence, the correct answer is (d) 9/5.
