The linear function for predicting the demand of an outdoor jacket is $F(t)=625+45t$ with the seasonal relatives $Q1=0\mathrm{.}2,Q2=0\mathrm{.}8,Q3=1\mathrm{.}2,$ and $Q4=1\mathrm{.}8.$ If the forecast for the third quarter of $2024$ is $1,344,$ which quarter should be the one when $t=3?$ :$\text{'}{Q}_3=1\mathrm{.}2$
