Answer 1

Answer:

answer is 15

cuz the sum of no.s around 12 is less than the sum nos around 20.

And the sum of nos around (?) is less than the sum of nos around 20 but more than the sum of nos around 12 ,

this is the only possible solution I could get

the ? is a number 12< ? <20

and the only option that satisfies that criteria is 15

so ?=15

Hopefully understandable ^-^.

brainliest please!
