Answer:

Step-by-step explanation:
Convert each to a improper fraction



SOLUTION
From the sequence give
–3, 1, 5, 9, . . .
The first term, a = -3
The common difference, d = 4 (gotten by adding 4 to the next term).
The number of terms required n = 6.
Formula for sum of an arithmetic sequence is given by

Substituting these values into the equation above we have

Hence, the answer is 42, option B
The answerrRRRRRRRRRRRRRRRRRRRR is A
I hope you have heard about the congruency rules like SSS, SAS, ASA
Those are the least amount of information you need
Answer: See the description below.
The residuals are the difference between the actual and predicted values. Just subtract those values and plot the point.
