Question

Find the term named in the problem: 4,0, -4,-3, ...Find a40

Answer 1

Let's begin by listing out the information given to us:

`\begin{gathered} a_1=4 \\ a_2=_{}a_1-4=4-4=0_{} \\ a_3=_{}a_1-4(2)=4-8 \\ a_4=_{}a_1-4(3)=4-12=-8 \\ \\ a_n=a_1-4(n-1)_{} \\ a_(40)=4-4(40-1)=4-4(39) \\ a_(40)=4-156=-152 \\ a_(40)=-152 \end{gathered}`

Hence, option D is the correct answer
