Question

Find the analogous pair of $(4,10,15)$ from the given alternatives.

• A. $(3,6,12)$
• B. $(2,8,10)$
• C. $(5,12,18)$
• D. $(7,10,18)$

Answer 1

The correct option is C $(5,12,18)$

The relation is as follows:
If the first numbet is $x$,
The second number is obtained by adding 1 to the first number and multiplying it by two.$\left[\right(x+1)\times 2]$
And the third number is obtaind by adding 1 to the first number and multiplying it by three.$\left[\right(x+1)\times 3]$
$x,\left[\right(x+1)\times 2],\left[\right(x+1)\times 3]$
$(5,[(5+1)\times 2],[(5+1)\times 3\left]\right)\Rightarrow (5,12,18)$
