Answer:To find the sum of the first 100 positive integers, you can use the formula for the sum of an arithmetic series:=2×(+)S n = 2n ×(a+l)Where:S n is the sum of the seriesn is the number of termsa is the first terml is the last termFor the numbers from 1 to 100:=100n=100=1 a=1=100l=100Now, plug in the values:100=1002×(1+100)=50×101=5050S 100 = 2100 ×(1+100)=50×101=5050So, the sum of the numbers from 1 to 100 is 5050.
