Insert 7

Insert five harmonic means between 3 and 18

Correct answer:

a2 =  3.4839
a3 =  4.1538
a4 =  5.1429
a5 =  6.75
a6 =  9.8182

Step-by-step explanation:

b6=b5+d=0.1481+(0.0463)=111080.1019 a6=1/b6=1/0.1019=10811=99119.8182   Verifying Solution:  B7=b6+d=0.1019+(0.0463)=1180.0556 A7=1/B7=1/0.0556=18
