Answer:

a)


\begin{gathered} \text{ Sum= 59,000+8,000=67,000} \\ \text{ Difference= 59,000-8,000=51,000} \end{gathered}

Explanation:

Rounding off 59,123 to thousands:


\text{ As its 100th term is 1, so 59,123}\approx59,000

Rounding off 7,854


\text{ As its 100th term is 8, so 7,854}\approx8,000

Therefore, the sum and difference of the given:

a)


\begin{gathered} \text{ Sum= 59,000+8,000=67,000} \\ \text{ Difference= 59,000-8,000=51,000} \end{gathered}
