Complete the square and write the equation in standard form. then give the center and radius of the circle. 10x2 + 10y2 = 100 question 20 options: x2 + y2 = 10 (0, 0), r = 10 x2 + y2 = 10 (0, 0), r = x2 + y2 = 100 (0, 0), r = 10 (x - 10)2 +(y - 10)2 = 10 (10, 10), r =

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
