Simplify the expression:

2(3 + g) =

6 + 2g

Step-by-step explanation:

whenever you have a problem like that you have to distribute the 2 to both the numbers in the parenthesis. You have to multiply 2 by 3 which is 6. Then you multiply 2 by g and you get 2g. We can't get any further so the simplified expression would be 6 + 2g

whats the question?

step-by-step explanation:

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
