Integers From 1-50. With Solution

Integers from 1-50. with solution

 

Answer:

The sum of 50 integers from 1-50 is 1,275.

Step-by-step explanation:

Sum of arithmetic sequence:

Sn = n/2 a₁ + an

Where:

Sn = sum of the sequence ⇒ unknown

n = number of terms/number of integers from 1 to 50 ⇒ 50

a₁ =  first term ⇒ 1

an = last term ⇒ 50

Find the sum:

S₅₀ = 50/2 (1 + 50)

S₅₀ = 25 (51)

S₅₀ = 1,275
