Question

[ 35+ (5×9)÷ 8 +4 / ( -8/3 + 13/4) ÷2] ÷6​

Answer 1

Answer:

Interesting question for me.

Here we can see that the sequence. I have to find value of X . If i can say in one sentence this will be 1st digit to add + 1 & next digit to add - 1.

4, 9 , 17, 35, 69, 139, 277 (X=139).

(4×2) + 1= 8 + 1 = 9

(9×2) - 1= 18 - 1 = 17

(17×2) + 1 = 34 + 1 = 35

(35×2) - 1 = 70 - 1 = 69

(69×2) + 1 = 138 + 1 = 139

(139×2) - 1 = 278 - 1 = 277

So, the value of X in the sequence 4, 9, 17, 35, 69, 139, 277.

Ans is X= 139.

I hope it's clear to you everyone.

Thanks.
