Step-by-step explanation:

$\blue{\underline{\large{given}}:}mean \: of \: five \: numbers = 80 \\ mean \: of \: 4 \: numbers = 46 \\ \blue{\underline{\large{To find}}:} 5th number \\ \blue{\underline{\large{Finding}}:} let \: the \: 5th \: number = x \\ mean \: of \: 4 \: numbers = 46 \\ \frac{sum \: of \: 4 \: numbers }{4} = 46 \\ sum \: of \: 4 \: numbers = 46 \times 4 = 184 \\ mean \: of \: 5 \: numbers = 80 \\ \frac{sum \: of \: 5 \: number}{5} = 80 \\ \frac{sum \: of \:4 \: number + x}{5} = 80 \\ sum \: of \:4 \: number + x = 400 \\ 184 + x = 400\\ x = 216</p><p>$
