A scientist collected data on the flight of a beetle. The data was then used to create the graph below. Based on the graph, what was the beetle's average flight speed?

1 meter per second, or 1m/s

Step-by-step explanation:

The average speed would be the total distance over the total time, 5/5 = 1, so the average flight speed is 1 meter per second, 1m/s

i believe the correct answer is b.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
