2 tickets cost 14.how many tickets can you buy with $63

9

Step-by-step explanation

x=number of tickets.

If 2x=14 divide each side by 2 to isolate x

2x/2=14/2

x=7

Now you know that each ticket costs 7.

y- number of tickets you can buy

so how many can you buy with $63?

7y=63 divide both sides by 7 to isolate for x

7y/7 = 63/7

x=9

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
