Question

Find the analogous pair for $(2,5,15)$ from the given alternatives.

• A. $(7,10,13)$
• B. $(3,8,24)$
• C. $(3,6,18)$
• D. $(4,5,9)$

Answer 1

Answer: (B)

$(3,8,24)$

The given triplet is $(2,5,15)$

Here second number is one less than the three times of first number and the third number is three times the second number.Mathematically,

$\Rightarrow (3\times 2)-1=5$ and $3\times 5=15$

A similar relation exists in the option $B$, where

$\Rightarrow (3\times 3)-1=8$ and $3\times 8=24$

Hence the correct answer is option $B$
