use this
Step-by-step explanation:
math wa
x=1 or -1/2
The value of x is 1 or -1/2
need a pictuer
-1078
To find the nth term in an arithmetic sequence we use the following formula
aₙ=a₁+(n-1)*d
Where a₁ is the first time, and d is the common difference (in this case -20)
So we have
2+(55-1)*-20
2+(54)*-20
2-1080
(X+7/4)=1/16
.
