Question

If the third of 7 consecutive numbers is 12,what is their sum?

Answer 1

Step-by-step explanation:

the third of 7 consecutive numbers is 12.

so, this looks like

..., ..., 12, ..., ..., ..., ...

that means the numbers have to be

10, 11, 12, 13, 14, 15, 16

the sum is then

16+10 + 15+11 + 14+12 + 13 = 3×26 + 13 = 91
