Find the next two numbers of 729, 243, 81

The numbers keep getting divided by 3.

729÷3=243÷3=81÷3=27.

27 and 9

Step-by-step explanation:

The formula for the nth term of a geometric sequence is

aₙ = a₁rⁿ⁻¹

We can get the value for r by dividing aₙ by aₙ₋₁.

a₃/a₂ = 81/243

a₃/a₂ = 1/3

r = 1/3

aₙ = 729(⅓)ⁿ⁻¹

a₄ = 729(⅓)⁴⁻¹

a₄ = 729(⅓)³

a₄ = 729 × 1/27

a₄ = 27

a₅ = 729(⅓)⁵⁻¹

a₅ = 729(⅓)⁴

a₅ = 729 × 1/81

a₅ = 9

The next two terms are 27 and 9.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

dhruv⭐

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
