Which number will replace the question mark (?) in the following series?
3, 7, 16, 35, ?, 153
Lets try to figure out the pattern in the series.
3
$$(3 \times 2) + 1 = 7$$
$$(7 \times 2) + 2 = 16$$
$$(16 \times 2) + 3 = 35$$
$$(35 \times 2) + 4 = 74$$
$$(74 \times 2) + 5 = 153$$
So , the answer would be Option b)74.
