Given the description of the sequence, write the first four terms in the numeric sequence. A geometric sequence with a common ratio of -3 and an initial term of 3

3, -9, 27, -81

Step-by-step explanation:

Multiply -3 everytime starting from 3.

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
