find the value of 1+2+3+4+............+100

$\huge{\mathfrak{\red{Answer}}}$

->

$sum \: from \: 1 \: to \: n \: =</em></strong><strong><em> </em></strong><strong><em>\frac{n(n + 1)}{2}$

now ,

n = 100

then by the formula

sum of 1 to 100 = $\frac{100(100 + 1)}{2}$

= $\frac{100 \times 101}{2}$

= 50 × 101

= 5050
