For #22, you add the fractions in the parentheses first. Since they don’t have the same denominator, you find a common denominator by multiplying 3/4 by 3 and 5/3 by 4. This will give you 9/12 and 20/12. So you now add these two fractions together to get 29/12, which simplifies to 2 5/12. You now have -2/3 + 29/12. -2/3 can be changed to -8/12 by multiplying it by 4 so that they have common denominators. The equation is now -8/12 + 29/12 . Since -8/12 is a negative number, you subtract 8 from 29 to get 21/12. 21/12 can be simplified to 7/4 by diving it by 3. The answer for #22 is 7/4.

Find the 73rd term of the arithmetic sequence -28, -41, -54, ...
PolarNik [594]

Answer:

the 73rd term of the arithmetic sequence is -964.

Step-by-step explanation:

The common difference in this arithmetic sequence is 13.  This is obtained by subtracting 28 from 41.  The first term is a(1) = -28.

The arithmetic sequence formula is a(n) = a(1) + d(n - 1), where d is the common difference and -28 the first term.

Then, in this case, a(n) = -28 - 13(n - 1), and

a(73) = -28 - 13(73 - 1) = -964
