Question

how to distinguish problem of arithmetic prigression, quadratic equation and linear equation

Answer 1

AP: In this type of questions u would find that they are in a pattern; here we have two terms common difference,d and first term,a
QUADRATIC EQUATION V/S LINEAR EQUATION: In quadratic equations we use only one variable,
ex:
${x}^{2} + x - 2$
here we have used only one variable i.e. x, whereas in linear equation we use two types of variables,
ex:
$2x + y = 2$
here we have used two variables x and y.
