Question

What is a formula for the nth term of the given sequence?
-20, -26, -32...

Answer 1

`x_(n) = x_((n-1)) -6`

Explanation:

b/c

Answer 2

Answer: aₙ=-14-6n

Explanation:

the common difference is :

d=-26-(-20)=-6

the nth term is aₙ=a₁+(n-1)d

a₁= -20

aₙ= -20+(n-1)(-6)

aₙ=-20-6n+6=-14-6n
