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

Answer:
21 - 3 + 18 ÷ 6 = 21
7 x 9 - 3 x 4 + 10 = 61
Step-by-step explanation:
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
