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

rounding to the nearest thousandth would be 452,000

x does not change; y increases by 12.
