isnt the change in flux into the page so the induced mag field is out of the page, thus current going anticlockwise?

In this case, the final flux would be 0 if the coil was completely removed from the magnetic field, and initial flux is into the page.
Change in flux = 0 - into the page = out of page
To oppose this change, a magnetic field into the page will be induced, hence current flows clockwise.

PS: One more question how is

Infinite summation can be a little more complicated than finite summation, in this case, the summation is defined in a certain way called Ramanujan Summation where even certain sums that go off to infinity converge, just like this one.
