In Exercises 1–14, write the first six terms of each arithmetic sequence. an = an-1 -0.4, a₁ = 1.6

Accepted Answer

enumerate the first five terms of the arithmetic sequence. Given the following values. Where a. N. Is equal to a n minus one minus 0.8 and a one equals 3.2. So when they find the first five terms of this sequence, Well our first term is a one. Will she know it's 3.2. Now by our equation A two is gonna be equal to a 2 -1 -0.8. In other words It is a 1 -0.8. Now we know what a one is, a one is 3.2. A two is an equal to 3. -0.8. That equals 2.4. Now we will do the same with a three. A three will be a 3 -1 -0. which is a three equals A 2 -3.8. What we said a two was 2.4 so a three is 2.4 -0.8 which is 1.6. You follow this pattern. A four Will be 8, -0.8 Which is 1.6 -0.8 or 0.8. Finally a 5% 5th term This will be 84 -0. Which gives us 0.8 -0.8 which is equal to zero. Now we have all of our values, we have a 13.2 A two which is 2.4. A three is 1.6 A 0.8850. This is the sequence of our first five terms. Sorry, answer to our problem is answer C. Okay. I hope I hope you solve the problem. Thank you for watching. Goodbye.
