Which amount of time is the shortest? 270 minutes 3 hours, 50 minutes 4 hours, 10 minutes 250 minutes

, 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

, and for

i think it might be a but you might want a second opinion

3x^3-2x^2+4x-3= -3

x^2+3x+3= 3

-3÷3= -1

answer: the answer is 84.

step-by-step explanation: i just answered it and 84 is correct. look at the graph and it should be the number between 2 points on the graph.
