What is the explicit rule for the sequence?

−114,−109,−104,−99,...−114,−109,−104,−99,...

 

  • an = 5n −119 
  • an = −5n − 119
  • an = 5n − 109
  • an = −5n − 109

To find any term we can write

 

an  =  -114 + 5 (n - 1)

 

However....simplifying this we get

 

an =  -114 + 5n - 5

 

an =  - 119  + 5n   =    5n - 119
