In the expression 2(4x + 6) = 78, what is the number you divide by at the end to get the answer?

8

Step-by-step explanation:

first we will just solve the expression 2(4x +6)=78

1. use destributive property with 2(4x + 6)

2*4x=8x

2*6=12

(8x+12)=78

2. now that the expression is simplified down we will subtract 6 by 6 to isolate it  

6-6+=0

78-6=72

3. now we can divide 8x by 8 also divide 78 by 8

8x/8=0

78/8= 9.75

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
