The first term of a sequence is 4 and the common ratio is -2. What is the formula for the sequence
based on term number
An =-2.(4)2-1
ar = 4.(-2)»–1
An = (4.- 2)241
an = 4.(-2)
DONE

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
