The sequence:
a 1 = 27 ft, a 2 = 18 ft, a 3 = 12 ft.
a 2 = a 1 * q
q = a 2 / a 1 = 18 / 27 = 2 / 3
a 4 = a 3 * q = 12 * 2 / 3 = 8 ft

Answer:
a. -216, 0 real roots
Step-by-step explanation:
The discriminant of ...
ax² + bx + c = 0
is ...
d = b² -4ac
When we put your equation into the standard form shown above, we get ...
7n² +8n +10 = 0
Then we can identify a=7, b=8, c=10. The discriminant is then ...
d = 8² - 4·7·10 = 64 -280 = -216
___
The interpretation of the discriminant is ...
- < 0; no real roots (2 complex roots)
- = 0; one real root (multiplicity 2)
- > 0; 2 real roots
Your discriminant is -216, so there are 0 real roots.
