raden · Answer

let that numbers are x, x+1 respectively. so we have an equation :
x + x + 1 = 113
solve for x, first

raden · Answer

100 and 12 ?
consecutive numbers like 12 and 13, 15 and 16, 99 and 100, 100 and 101

anonymous · Answer

Ohh. 99 and 13?

raden · Answer

just solve this with  of algebra
x + x + 1 = 113, can you ?

anonymous · Answer

BTW, here are the choices I can choose from. 
2x = 113
2x + 1 = 113
2x + 2 = 113
x2 + 1= 113

raden · Answer

it is the second one, combine the similar terms
x + x + 1 = 113
2x +  1 = 113

raden · Answer

now solve for x

anonymous · Answer

Makes so much sense now! Is it 56?

raden · Answer

hehe, correct. x = 56
and the second number is x + 1 = 56 + 1 = 57
s0, they are 56 and 57 resepectively
