Question

Find the analogous pair for $(2,10,28)$ from the given alternatives.

• A. $(4,20,56)$
• B. $(7,42,49)$
• C. $(12,24,48)$
• D. $(9,27,81)$

Answer 1

The correct option is A $(4,20,56)$

The relation is as follows:
If the first number is $x$,
the second number is 5 times the first number $(x\times 5)$
the third number is 14 times the first number $(x\times 14)$
$(x,(x\times 5),(x\times 14\left)\right)$
$(4,[4\times 5],[4\times 14\left]\right)\Rightarrow (4,20,56)$
