Solution

The correct option is B $233$
Givens series is: $7, 15, 28, 59, 114, (?)$
Here, we have
$15 = 7 \times 2 + 1$
$28 = 15 \times 2 - 2$
$59 = 28 \times 2 + 3$
$114 = 59 \times 2 - 4$
Now, let the missing number be $x$
Therefore, $x = 114 \times 2 + 5 = 233$
Hence, option (B) is the correct answer.
