answer: no real solution
x^2 - 6 + 9 = 0
step 1: simplify both sides of the equation.
step 2: subtract 3 from both sides.
step 3: take square root. x=±√−3
answer is no real solutions.
to find recursive formula in a geometric sequence, you need to first find the common ratio, 'r', between the numbers in the given data set. from the data set given, it appears that the previous number is multiplied by so, r = .
recursive formula involves two other variables:
the term in the sequence
=the term before the term
so, the final formula is:
(x - 10)/4
let x = -18
(-18 - 10)/4
