So to get from 4 to 8 you multiply by 2. To get from 8 to 16 you multiply by 2. So for the missing number, 10 times 2=20. The missing number should be 20. To check our work, 20 times 2 equals 40. So the missing number is 20. Hope this helps! ;)

Gekata [30.6K]

Answer:

A. A(n) = 150 • (0.74)^n–1 ; 33.29 cm

Step-by-step explanation:

This is a geometric sequence.

a%5B1%5D=1.5m=150cm, r=0.74

The formula is

a%5Bn%5D=a%5B1%5Dr%5E%28n-1%29

Just substitute a1 = 150cm and r = 0.74

a%5Bn%5D=150%280.74%29%5E%28n-1%29

That's the rule.

For the second part, substitute n = 6
