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.

1 1/4 hours

step-by-step explanation:

2/4 + 2/4 + 1/4 = 5/4 or 1 1/4

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
