Square roots of 17^2-10^2
=13.74772708
= 13.7 the nearest tenth
Answer:
A)6, 2, -2,-6
Step-by-step explanation:
a(n) = a +(n-1)d
a(n) = a +dn-d
a(n) = a-d + dn
a(n) = 10 - 4n
So d=-4
to get a: (a-d)=10
a=10-4=6
The first four terms:
a(1) = 6 +(1-1)-4=6
a(2) = 6 +(2-1)-4=2
a(3) = 6 +(3-1)-4=-2
a(4) = 6 +(4-1)-4=-6
it will be A
hope this helps
A) 3d, 4d
should be your answer
since all of them have "d" in them

An=Asub1+d(n-1)
Asub5= -5+½(4)
=-5+7
=2
is approximately 0.14!
