Question

RThe sum of five consecutive integers is 330. What is the least integer?

Answer 1

The least integer is 64

Explanation:

Let x+(x+1)+(x+2)+(x+3)+(x+4)=330

Open the bracket and collect like terms

x+x+x+x+x+1+2+3+4=330

5x+10=330

5x=330-10

5x=320

Divide both sides by 5

x=64

Answer 2

64

Explanation:

Let x = smallest one

x + x+1 + x+2 + x+3 +x+4 = 330

5x + 10 = 330

5x = 320

x = 64
