Question

The sum of seven consecutive numbers is 175. What is the difference between twice the largest number and thrice the smallest number?​

Answer 1

Let us assume the Numbers to be

X , ( X + 1 ) , (X + 2 ) , ( X + 3 ) , ( X +4 ) , ( X + 5 ) , ( X + 6 )

According to the given question:

X + X + 1 + X + 2 + X + 3 + X + 4 + X + 5 + X + 6 = 175

7X + 21 = 175

7X = 175 - 21

7X = 154

X = 22

⏪Largest Number = X + 6 = 28

⏪Smallest Number X = 22

Difference between 3(28) and 22

84- 22

= 62
