Question

.What is the nth term rule of the linear sequence below? 22 , 18 , 14 , 10 , 6 , . . .

Answer 1

Answer:

$a_n=26-4n$

Step-by-step explanation:

The nth term of an AP is

$a_n=a+(n-1)d$

where, a is the first term of the sequence and d is common difference.

The given linear sequence is

22 , 18 , 14 , 10 , 6 , . . .

Here, first term is 22 and common difference is

$d=a_2-a_1=18-22=-4$

The common difference of the sequence is -4. So, the nth term of given sequence is

$a_n=22+(n-1)(-4)$

$a_n=22-4n+4$

$a_n=26-4n$

Therefore, the nth term of the sequence is $a_n=26-4n$.

Answer 2

N+4
how do I get it ?
put the 6 into n
(6)+4=10
so answer is n+4
