1. Find the 25th term of the arithmetic sequence ‒7, ‒4, ‒1, 2, ... 2. In an arithmetic sequence, if a4 = 18 and a10 = 30, determine a1, d, and an. Then write the first four terms of the sequence. 3. In a geometric sequence, if a3 = ‒5 and a6 = 40, determine a1, r, and an. Then write the first three terms of the sequence.

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
