Answer:
The first term of the sequence is -120.
Step-by-step explanation:
The formula for the "nth" term of a geometric sequence is shown below:
an = a0*r^(n-1)
Where an is the nth term, r is the ratio and n is the position of the term on the sequence. For this problem we want to find what is the initial term, a0, so we will isolate it in the formula as shown below:
a0*r^(n-1) = an
a0 = an/[r^(n-1)]
We then apply the data given to us
a0 = 31.45728/[-0.8^(7-1)]
a0 = 31.45728/[-0.8^6] =31.45728 /-0.262144= -120
The first term of the sequence is -120.
So, for the first variable, you would use x, and for the second, y. Then, you would write out 2-(3y)=14. once this is done, youd simplify to 2-3y=14. Subtract 2 from both sides to get 3y=12. Then, divide both sides by 3. this will leave you with y=4. From this you can see the other number is ten. Hope this helped! and i apologize if it is incorrect!
100-24=76
76%=76/100=0.76
single multiplier=0.76
