Sequence 2

Write the first 6 members of an arithmetic sequence a3=-2, d=-5.

Final Answer:

x1 =  8
x2 =  3
x3 =  -2
x4 =  -7
x5 =  -12
x6 =  -17

Step-by-step explanation:

d=−5 x3​=−2 x1​=x3​−(3−1)⋅ d=(−2)−(3−1)⋅ (−5)=8
x2​=x1​+d=8+(−5)=3
x3​=x2​+d=3+(−5)=−2
x4​=x3​+d=(−2)+(−5)=−7
x5​=x4​+d=(−7)+(−5)=−12
x6​=x5​+d=(−12)+(−5)=−17
