Can someone explain 2D.1?
Place the following elements in order of increasing electronegativity: antimony, tin, selenium, and indium.

I thought it was tin<antimony<tellurium<selenium

I believe you have mistakenly replaced indium with tellerium in your final answer. The correct answer is In<Sn<Sb<Se, which you should have arrived at based on your thought process if you didn't switch up the two elements

Electronegativity increases as you go down to a group and decreases as you go across a period.

Electronegativity decreases down a group and across a period, so just look at the positions of the elements on the periodic table.

The elements in order of increasing electronegativity are indium, tin, antimony, selenium because electronegativity increases up a group and as you move to the right of a period.
