Step-by-step explanation:
We get tne n-th term with: tn=1/3tn-1
We know that the first term is t1=81, so 81=1/3t*1-1
81=1/3t-1
82=1/3t
82*3t=1
3t=1/82
t=1/82*3=1/246
The second term is: 1/
2*(1/246)*2)-1
We get the third term by replacing n with 3 and so on...
Answer:
<u>x = −
69</u>
Step-by-step explanation:
1: Simplify
−2x−(10)(12)=18
−2x+−120=18
−2x−120=18
2: Add 120 to both sides.
−2x−120+120=18+120
−2x = 138
3: Divide both sides by -2.
-2x ÷ -2 = 138 ÷ -2
x = −69
