Question

Sum of 3 consecutive numbers is 87, fiind the largest no

Answer 1

Answer:

Then 3x+3=87

Then 3x=84

So x=28

Then The largest no. is 28+2=30......

Answer 2

Okay, Okay it's an interesting question see,

If it's said that sum of 3 CONSECUTIVE numbers is 87, We can assume them

$x .(x + 1) \: and(x + 2)$

*.refers to ','*

Now make the equation:

X + (X+1) + (X+2) = 87

$= 3x + 3 = 87 \\ = 3x = 87 - 3 \\ = 3x = 8</strong><strong>4</strong><strong> \\ = x = 8</strong><strong>4</strong><strong> \div 3 \\ = x = 28$

Now put the value in the largest no. "X+2"

28 + 2 = 30

Therefore the largest no. is 30
