we have

5,15 \\6, 18 \\7,21 \\8,?

Let

a1=5\\b1=15\\a2=3\\b2=18\\a3=7\\b3=21\\a4=8

we know that

\frac{b1}{a1}=\frac{15}{5}\\ \\b1=3*a1

\frac{b2}{a2}=\frac{18}{6}\\ \\b2=3*a2

\frac{b3}{a3}=\frac{21}{7}\\ \\b3=3*a3

a4=8

so

the next term should be

b4=3*a4=3*8=24

therefore

<u>the answer is</u>

24
