What is the difference between the absolute value of -10 and the absolute value
of 6?

The absolute value of 10 is 10. The absolute value of 6 is six.

The difference of 4.

Step-by-step explanation: The absolute value of -10 is 10, and the absolute value of 6 is 6. If you subtracted 6 from 10 (10-6), you would get 4, and that is the difference.

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
