Given the sequence 2,6, 10, 14,... what term number has the value of 166?

Step-by-step explanation:

these number grow by four every time

Y N

1 -2

2 - 6

3- 10

4- 14

N= 4× Y

2= 4 × 1

2= 4

2-4= -2

4× N + -2

4 × 42+ -2

168- -2= 166

Therefore the term of 166 will be 42.

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
