Answer:
C. 300
Step-by-step explanation:
6. What is the 71st term in the sequence 20, 24, 28, 32 ...?
Given:
n = 71
a₁ = 20
d = a₂-a₁
= 24 - 20
= 4
Formula:
[tex]a_{n} =a_{1} +(n-1)d[/tex]
Solution:
[tex]a_{n} =a_{1} +(n-1)d[/tex]
[tex]a_{n} =20 +(71-1)4[/tex]
[tex]a_{71}=20+(70)4[/tex]
[tex]a_{71} =20+280[/tex]
[tex]a_{71} =300[/tex]
