Answer: -3n-2.
Because for the first term, for example, plug in 1, you'll get -3(1)-2=-3-2=-5, which is the first one. Try it with all terms.
Answer:
1
Step-by-step explanation:
i (a + bi) = 1
ai + b(-1) = 1
ai − b = 1
Match the coefficients.
ai = 0
-b = 1
Therefore, a = 0 and b = -1.
So a − b = 0 − (-1) = 1.
Answer:
where r yr series
Step-by-step explanation:
For example, the sequence 3, 5, 7, 9 ... is arithmetic because the difference between consecutive terms is always two. The sequence 21, 16, 11, 6 ... is arithmetic as well because the difference between consecutive terms is always minus five.
