James has noticed that the number of new tree branches that have grown on a tree in his backyard each year follows the sequence
eduard

Notice that the pattern is "previous term plus 2".  This is an arithmetic sequence where the difference (d) equals +2

a_{n} = a₁ + d(n - 1)   ; where a₁ is the first term, d is the difference, and n is the term.

f(n) = 1 + 2(n - 1)

f(n) = 1 + 2n - 2

f(n) = 2n - 1

********************************

f(10) = 2(10) - 1

f(10) = 20 - 1

f(10) = 19

Which of the following is a solution of x^2 - 2x = -8?
Zina [86]
X^2-2x=-8  add 1 to both sides

x^2-2x+1=-7  now the left side is a perfect square

(x-1)^2=-7  take the square root of both sides

x-1=±√-7  add 1 to both sides

x=1±√-7 which is

x=1±i√7  so

x=1+i√7 and 1-i√7
