Answer 1

If the sum is -200 and the one number is 98 then the other number must be -298 because if we add -298 + 98 = -200

so the other number is -298

Answer 2

Let , The unknown number be x

$\underline \bold{ \: According \: to \: the \: question \: ,\: }$

$\bold{ \to \: 98 + x = - 200} \\ \\ \bold{ \to \: x = - 200 - 98} \\ \\ \bold{\to \: x = - 298}$

$\therefore$ The required number is -298
