Answer 2

Hello !!

For you find the sum of the first 10 natural numbers, you can make use of this formula.

Sn = (n/2) × [2A1 + (n - 1) × d]

Find the common difference.

d = (An - Ak)/(n - k)

d = (2 - 1)/(2 - 1)

d = 1/1

d = 1

Now, we calculate the sum of the first 10 natural numbers.

Sn = (n/2) × [2A1 + (n - 1) × d]

S10 = (10/2) × [2(1) + (10 - 1) × 1]

S10 = 5 × [2 + 9 × 1]

S10 = 5 × [2 + 9]

S10 = 5 × 11

S10 = 55

Final result : 55 is the sum of the first 10 natural numbers.

I hope I have collaborated !
