Answer:
If the n-th term of a sequence be , t(n) equal to then the 5-th term is 27 but if the n-th term is (2n -n) then the 5-th term is 5.
Step-by-step explanation:
If the n-th term of a sequence be , t(n) =
then, the 5-th term is given by, t(5) =
= 32 - 5
= 27
If the n-th term of a sequence be , t(n) = 2n - n = n
then, the 5-th term is given by, t(5) = 5

Answer:
Of the 600 elephants that he observes in random places in the reserve, he counts elephants with broken tusks.
Step-by-step explanation:
Let x denotes number of elephants having broken tusks out of 600 elephants.
Of the 30 elephants that he observes in random places in the reserve, he counts 8 elephants with broken tusks.
So,
Of the 1 elephants that he observes in random places in the reserve, he counts elephants with broken tusks.
Therefore,
Of the 600 elephants that he observes in random places in the reserve, he counts elephants with broken tusks.
