Use your formula from question 2c to find the values of t7 and t20. (r=7; 2,14,98,686) (Geometric Sequence)

Correct  t₇ -  a₇ = 2 · 7⁶,  t₂₀ - a₂₀ = 2 · 7¹⁹

Step-by-step explanation:

Given:

Geometric sequence  2, 14, 98, 686,

First term is a₁ = 2

Second term a₂ = 14

Third term a₃ = 98

The quotient ( ratio) is obtained as follows:

r = 14 / 2 = 98 / 14 = 7

r = 7

n-th term is obtained as follows:

aₙ = a₁ · rⁿ⁻¹

according to this:

a₇ = 2 · 7⁶ = 2 · 117,649 = 235,298

a₂₀ = 2 · 7¹⁹ = 2 · 11,398,895,185,373,143 = 22,797,790,370,746,286

God is with you!!!

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
