Translate the statement shown into a mathematical expression “15 less than the product Of 2 and X

2x - 15

Step-by-step explanation:

The mathematical equivalent of the expression less than is given by the signal -

For example

2 less than 3, mathematically, is given by:

3 - 2

In this problem, we have that

“15 less than the product Of 2 and X"

The product of 2 and x is 2x.

So the mathematical representation of this statement is:

2x - 15

168

step-by-step explanation:

i am pretty sure that the answer is 168

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
