Answer 1

সঠিক উত্তর হচ্ছে: 25

ব্যাখ্যা: Let us observe the sequence,
5,7,10,14,19
The difference between first 2 numbers = 7-5=2
The difference between next 2 numbers = 10-7=3
The difference between next 2 numbers = 14-10=4
The difference between next 2 numbers = 19-14=5
So logically, the difference between any two consecutive number is gradually increasing by 1.
Therefore difference between next 2 numbers should be 6
If x is the next number, then according to the above relation
x-19=6
i.e, x = 19+6 = 25.
