To find the common difference, we use the formula 
where
<em>a2</em> represents the second term and <em>a1</em> represents the first term.
So plugging the second term and first term into
the formula, we have (17) - (12) which is 5.
So the common difference of
this arithmetic sequence is 5.
Answer:
C
Step-by-step explanation:
given the factors are (x - 7) and (x + 3)
equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7

Whole number is are numbers like 0, 1, 2, 3, 4...... and so on
negatives, fractions, decimals, and irrational numbers are not whole numbers
so the whole number portion of the two numbers are <u> 5 and 418</u>
