Answer: 1/2, 4/8...
Step-by-step explanation: because the least factor is 1/2 so all the numbers and their multiplicity of 2.
X= 10
complementary angles= 90° so 90-50=40
40 ÷ 4= 10
I’m pretty sure it will be the last one f(x)=(3x+1)(2x-5).
This is geometric with a common ratio of 3 (3/1 = 3 and 9/3 = 3 etc)
the formula for the nth term is
an = 3^(n-1)
