Which equation represents this problem? The time it takes Tomás to bike to the community center is 2 minutes less than half the time it takes him to bike to the city park. It takes Tomas 18 minutes to bike to the community center. Let p = the time it takes Tomas to bike to the park A:2p+1/2=18
B:1/2p+2=18
C:2p-1/2=18
D:1/2p-2=18

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative

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
