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

Answer:

let the no.be x

so

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

= 7x+21=175

=7x=175-21

=7x=154

=x=154÷7

=x=22

so

twice of largest no.=(22+6)×2

= 28×2

=56

thrice the smallest no.=22×3

=66

the difference is 56-66=-10
