Answer 2

Given:

7, 40, 78, 126, 194, ?

To find:

value=?

Solution:

7, 40, 78, 126, 194, ?

Solve:

$\to 40 -7= 33\\\\\to 78-40= 38 \ \ \ if \ we \ add \ 5 \ in \ 33 = 38\\\\\to 126-78= 48 \ \ \ if \ we \ add \ 10 \ in \ 38 = 48\\\\\to 196-126= 68 \ \ \ if \ we \ add \ 20 \ in \ 48 = 68$

similarly:

$\to 302-194= 108$

if we add the double value of the difference so it will become 108:

last difference= 20

double value = 40

$\to 68+40 =108$

The final answer is "302".
