42,36,60,25,22,?,7,29,28,35,55,105,100,49,79,3 find the missing numbr​

Answer 1

Answer:

Here, we add the sum of last two columns of the elements and divide it by 2 which must be equal to the sum of the elements of the first two columns.

For example, let us apply this algorithm in the given question.

[(42+36+60+25)+(22+?+7+49)]/2=[(28+35+55+105)+(100+49+79+43)]/2

⇒241+?=247

⇒?=6
