In the following question, one number in the number series is...

The given series is $4,25,100,289,652,1369,2500$ Here, we have to find out the odd number in the given number series. By analyzing the given series we can say that all the given numbers are the perfect square except one number ie.652. Here, $$\begin{aligned} & 2^2=4 \\ & 5^2=25 \\ & 10^2=100 \\ & 17^2=289 \\ & 37^2=1369 \\ & 50^2=2500 \end{aligned}$$ Thus, $26^2=676$ So, there should be 676 in place 652 in the given series. Hence, this is the correct answer.
