Answer:
4a (n-1) + 5
Step-by-step explanation:
1th=6
2nd=29
3rd=121
4th=489
.
.
nth
if n=2
a2 = 4a(2-1) + 5 = 4 a(1) + 5 = 4 (6) + 5= 29
a3 =4a(3-1) + 5 = 4 a(2) + 5 = 4 (29) + 5= 121
try finding a4, check wether the answer is 489
We have that
<span>6x^2 +12x+5=0
to find the x intercepts resolve the second order equation
x=[-b(+-)</span>√(b²-4ac)]/2a
x1=[-12(+)√(12²-4*6*5)]/12---> [-12(+)√(144-120)]/12
=[-12(+)√(24)]/12--------> -1+√24/12-----> -1+√6/6
x1=-1+√6/6
so
x2=-1-√6/6
see the graph in the attached figure
<span>
the answer is
</span>the x-intercepts for the graph of the quadratic function in <span>exact form are
</span>x1=-1+√6/6
x2=-1-√6/6
If the exponent is positive then you move the decimal to the right to make the number bigger. If the exponent is negative then you move the decimal to the left to make the number smaller.
