Answer 2

Answer:

The number comes next will be

7+8 = 98 why this number comes i explain look carefully.

After seeing the series 2+3=8 , 3+7=27_____ 7+8= ? a hidden method which is “ xy+xn “ where x is the first and y is the second number and n represent the turn or position or time means n represent on which position ,turn or time the number series comes.

Let's check the formula on the numbers of series

Total numbers of turn , position ( n ) = 1,2,3,4,5,6

2+3=8 { xy+xn , x first number( 2 ) , y second number ( 3 ) ,xy+xn =2×3+2×1 = 8 }

Here n =1 just because 2+3 got the first position of the series.

Let's apply this formula in the second number

3+7 =27 { x first number = 3 , y second number= 7 , xy+xn = 3×7+3×2= 27 }

Here n=2 just because 3+7 got second position .

Finally apply this formula on the question which ask from us in this question

7+8 = ? Here x first number = 7 , y second number = 8 , and n=6 just because 7+8 come on sixth position in the series so

7+8=98 { xy+xn = 7×8+7×6= 98 }
