Question

plz solve this problems

Answer 1

Hello User

This is NTSE stage 1 problem.

Observing the General pattern , we get..

(a + b + c)×5 - 1 = the number in between.


Applying this to the last triangle, we get

(6+10+5)×5 - 1 = ?

? = 105 - 1 = 104

So, option A is correct.


Hope it works.
