Answer:128

Step-by-step explanation:

If you look at the circle. The two ones that look most like rs is the 64's. Therefore using logic you can just add 64 plus 64 to get 128. Hope it helps.

Answer:

Temperature dropped by 28°C in two hours

Step-by-step explanation:

Initial measurement:

t = 17°C

Measurement 2 hours later:

t = - 11°C

The difference:

-11°C - 17°C = -28°C

Temperature dropped by 28°C in two hours

Choose the explicit and recursive formulas for the geometric sequence 45, 135, 405, 1215, 3645, .... PLEASE HELP ASAP

sesenic [268]

Answer:

Option (B)

Step-by-step explanation:

Given sequence is 45, 135, 405, 1215, 3645..........

Since it's a geometric sequence,

Common ratio of each successive term to the previous term

r = $\frac{135}{45}=3$

First term of the sequence 'a' = 45

Explicit formula of a geometric sequence will be,

$a_n=a(r)^{n-1}$

$a_n=45(3)^{n-1}$

Recursive formula of this sequence will be,

$a_n=3(a_{n-1})$ , $a_1=45$

Therefore, Option (B) will be the answer.
