What is a recursive rule for 320, 80, 20, 5, 1.25,

see explanation

Step-by-step explanation:

Note there is a common ratio r between consecutive terms in the sequence, that is

r = 80 ÷ 320 = 20 ÷ 80 = 5 ÷ 20 = 1.25 ÷ 5 = 0.25

Thus the sequence is geometric.

A recursive rule allows a term in the sequence to be found by multiplying the previous term by r, thus

= 0.25 with a₁ = 320

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
