Answer 1

Question:

• Find the sum of 1+2+3+........+60 .

Answer:

$\large\bold\red{1830}$

Explanation:

Here,

• We have to find the sum of first 60 natural numbers.

Now,

We know that,

• Sum of first n natural numbers is given by $\bold{\frac{n(n+1)}{2}}$

Therefore,

Sum of first 60 natural numbers is,

$= \frac{60(60 + 1)}{2} \\ \\ = \cancel \frac{60 \times 61}{2} \\ \\ = (30 \times 61)\\\\=1830$

Hence,

The required sum is 1830
