Question

the sum of a number and it's predecessor is 75​

Answer 1

Answer:

Let one of the number be x.

Then its predecessor will be x-1.

According to question:-

$x + x - 1 = 75 \\ \\ 2x - 1 = 75 \\ \\ 2x = 75 + 1 \\ \\ 2x = 76 \\ \\ x = \frac{76}{2} \\ \\ x = 38$

So the numbers are

X = 38

And

X - 1 = 38 - 1

= 37

Hope it helps.

Lets take the no 2

So the predecessor = 1 and the successor = 3

3+2+1= 6 which is divisible by 3
