Question

A n =−1+3(n−1) an=−1+3(n−1) what is the 55 term in the sequence

Answer 1

ANSWER


`a_(55)=161`


Step-by-step explanation

The general term for the sequence is



`a_n=-1+3(n-1)`


To find the 55th term, we have to substitute

`n = 55`
in to the general term and simplify.



This implies that,


`a_(55)=-1+3(55-1)`




`a_(55)=-1+3(54)`





`a_(55)=-1+162`




`a_(55)=161`


Therefore the 55th term is 161.
