Question

What are the first five terms of the arithmetic sequence

Answer 1

Answer: d : 11, 8, 5, 2, -1

Answer 2

Answer:

option d : 11, 8, 5, 2, -1

Step-by-step explanation:

Given a=14-3n

To get first term we plug in 1 for n

n=1  , $a_1= 14- 3(1)= 14-3=11$

n=2  , $a_2= 14- 3(2)= 14-6=8$

n=3  , $a_3= 14- 3(3)= 14-9=5$

n=4   , $a_4= 14- 3(4)= 14-12=2$

n=5   , $a_5= 14- 3(5)= 14-15=-1$

So first five terms are 11, 8, 5, 2, -1
