Answer 2

$\small\sf\underline\red{The\:odd\:numbers\:between\:0\:and\:50:1,3,5,....49}$

$\large\tt\pink{a=1,}$

$\large\tt\pink{d=3-1=2}$

$\large\tt\pink{n=25}$

$\small\sf\underline\red{The\:sum\:of\:n\:terms\:of\:an\:AP\:are\:given\:by}$

$\longrightarrow$$\large\tt\purple{Sn=\frac{n}{2}(2a+(n-1)d)}$

$\longrightarrow$$\large\tt\purple{S25=\frac{25}{2}(2(1)+(25-1)2)}$

$\longrightarrow$$\large\tt\purple{\frac{25}{2}(2+48)}$

$\longrightarrow$$\large\tt\purple{\frac{25}{2}(50)}$

$\longrightarrow$$\large{\boxed{\tt{\purple{625}}}}$
