Answer:
x = 2.4 or x = 0.3
Step-by-step explanation:
3x² - 8x + 2 = 0
Quadratic formula
x = {-b ±√b² - 4ac} / 2a
a = 3
b = -8
c = 2
x = {-b ±√b² - 4ac} / 2a
= {-(-8) ±√(-8)² - 4*3*2} / 2*3
= (8 ± √64 - 24) / 6
= (8 ± √40) / 6
= (8 ± 2√10) / 6
= 8/6 ± 2√10/6
= 4/3 ± √10 / 6
x = 4/3 + √10 / 6 or 4/3 - √10 / 6
x = 2.4 or x = 0.3

Answer:
An explicit rule for the nth term of the sequence will be:
Thus, option (A) is true.
Step-by-step explanation:
Given the sequence
A geometric sequence has a constant ratio r and is defined by
Computing the ratios of all the adjacent terms
As the ratio 'r' is the same.
so
as
Hence, the nth term of the sequence will be:
substituting the values and
Therefore, an explicit rule for the nth term of the sequence will be:
Thus, option (A) is true.
