Answer 1

$\huge \boxed {\texttt {\fcolorbox {red} {aqua} {SOLUTION :-}}}$

GIVEN, First term, a = 25

So, a20 = 500

=> a + 19 d = 500

=> 25 + 19d = 500

=> 19d = 500 - 25

=> d = 475 /19 = 25

Hence, the common difference, d = 25

Answer 2

GIVEN, First term, a = 25

So, a20 = 500

=> a + 19 d = 500

=> 25 + 19d = 500

=> 19d = 500 - 25

=> d = 475 /19 = 25

Hence, the common difference, d = 25
