Which of the following numbers will replace the question mark (?) in the given series?
3, 4, 10, 33, 136, ?

3, 4, 10, 33, 136, ?

Logic:  show below ...

3 $$\times$$ 1 + 1 = 4,     

4 $$\times$$ 2 + 2 = 10,  

10 $$\times$$ 3 + 3 = 33,

33 $$\times$$ 4 + 4 = 136,

136 $$\times$$ 5 + 5 = 685

So, that next number is 685.

Thus, correct option is (d)​​
