What are the explicit equation and domain for a geometric sequence with a first term of 5 and a second term of −10? an = 5(−2)n − 1; all integers where n ≥ 1 an = 5(−2)n − 1; all integers where n ≥ 0 an = 5(−15)n − 1; all integers where n ≥ 1 an = 5(−15)n − 1; all integers where n ≥ 0

is right.

Step-by-step explanation:

Given that in a geometric sequence the I term is 5 and second term is -10

If first term is a, then II term is ar where r is the common ratio

Hence r = II term/I term = -10/5 =-2

Using the geometric sequence formula for nth term

we have

Substitute to get nth term as

, for all integers n>=1

Hence option A is right answer

step-by-step explanation:

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
