Find the sum of the first 12 terms of the sequence. show all work for full credit. 1, -4, -9, -14, . . (2 points)

-348

Step-by-step explanation:

We are given the following arithmetic sequence and we are to find the sum of its first 12 terms:

1, -4, -9, -14, . . .

For that, we will use the formula for the sum of the arithmetic mean:

We know the value of the first term () but we need to find the value of . So we will use the following formula:

Substituting these values in the sum formula to get:

-348

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

c - they will have the same distribution

this is the only one that could make sense. : )
