Choose the option in which the relationship among the numbers is the same as in the given group of numbers: (26, 144, 18)

Given group:

$(26, 144, 18)$

Relation:

$26 + 18 = 44$

और

$44 \times 3 = 132$ → नहीं

दूसरा pattern check करें:

$26 - 18 = 8$

$8 \times 18 = 144$

Relation is:

$(पहला - तीसरा) \times तीसरा = दूसरा$

अब options check करें:

1. $(18,120,13)$
   $(18-13)\times13 = 5\times13 = 65 \neq 120$
2. $(28,190,16)$
   $(28-16)\times16 = 12\times16 = 192 \neq 190$
3. $(21,108,12)$
   $(21-12)\times12 = 9\times12 = 108$ ✓
4. $(31,196,24)$
   $(31-24)\times24 = 7\times24 = 168 \neq 196$

Correct answer: (21, 108, 12)
