Which pair of numbers is relatively prime?
Kazeer [188]

Answer: C. 625 and 81

Step-by-step explanation: A relatively prime pair is a pair in which in both numbers given, the only number that can go into each number is one. In 112 and 36, we know 2 can evenly go into each number because they both end in a positive number (112/2 is 56 and 36/2 is 18.) This means A is incorrect. As for B, 11 can evenly go into each number, leaving you with 25 and 7. B is incorrect. And then there's D. 5 can go into each number giving you 160 and 19. D is incorrect.

C is correct because the only numbers that can go evenly into 81 is 1, 3, 9, 27, and 81. None of these numbers, except one can go into 625 also.

What is an explicit formula for the geometric sequence -64,16,-4,1,... where the first term should be f(1).
nirvana33 [79]

Answer:

a_{n} = -64(-\frac{1}{4})^{n-1}

it seems like the first term is -64, so lets write the formula accordingly:

a_n = a1(r)^(n-1)

where 'n' is the number of terms

a1 is the first term of the sequence

'r' is the ratio

the ratio is -\frac{1}{4} because -64 * -\frac{1}{4} = 16 and so on...

the explicit formula is :

a_{n} = -64(-\frac{1}{4} )^{n-1}
