Questions: 1) Calculate the average number of immigrants per year if the period lasted exactly $62$ years. 2) Based on the text, what is the main motivation for these immigrants, and how does it relate to the concept of the 'American Dream'?

Read the following data regarding immigration flows: at the peak of Ellis Island in $1907$, approximately $1,004,756$ immigrants arrived. Consider a sub-group from Eastern Europe starting with $P_0 = 150,000$ in $1900$. The population of this group follows a geometric growth model $P_n = P_0 \times r^n$, where $r = 1.05$ is the annual growth factor and $n$ is the number of years since $1900$. Calculate the exact value of $P_7$ for the year $1907$ using the formula. Furthermore, write a short analytical paragraph (in English) discussing why the 'Memory of Migration' is a pillar of American identity, using at least two advanced linking words (e.g., 'notwithstanding', 'furthermore').
