Answer:
Option C.
Step-by-step explanation:
It is given that the first term of the arithmetic sequence is 8 and second term is 5.
We know that the explicit equation of an AP is
, where n is an integer greater than or equal to 1.
where, a is first term and d is common difference.
So, domain of this explicit equation is all integers where n ≥ 1.
Therefore, the correct option is C.

Answer:
72
Step-by-step explanation:
h(4) = 4^3 -2·4 = 64 -8 = 56
g(4) = 3·4 +4 = 16
Then the sum is ...
(h+g)(4) = h(4) + g(4) = 56 +16
(h+g)(4) = 72

It's more than 3600, so its greater than 60.
it's less than 4900, so its less than 70.
a no.'s root can end with six if the no. ends with 4 or 6.
so the no is either 64 or 66.
Now if it's 66, the square must be greater than sq of 65.
65 sq= 4225
the given no. is greater than sq of 65.
Therefore the number is 66.
