Question

6. The first, second and fourth terms of a proportion are 16, 24 and 54 respectively. Find the
third term​

Answer 1

Answer:

36

Step-by-step explanation:

Given that

a1=16

a2=24

a3=?

a4=54

there. a=16. r=a2/a1=24/16=3/2

a3=ar^(n-1)=a2×r

24×3/2=12×3=36

checking

a4=a3×r

=36×3/2

=18×3

=54

so the a3 term is 36
