Answer 1

Hi dear!

Question:

Find two consecutive number which sum 155.

Answer:

We know that consecutive number differ by one.

Let the consecutive numbers be x and x + 1.

According to your question,

Sum of these numbers = 155

x + x + 1 = 155

2x + 1 = 155

2x = 155 - 1

2x = 154

x = 154/2

x = 77

Hence,

The first number = x = 77

The second number = x + 1 = 77 + 1 = 78

Thanking You!

Answer 2

We know that consecutive number differ by one.


Let the consecutive numbers be x and x + 1.


According to your question,


Sum of these numbers = 155


x + x + 1 = 155


2x + 1 = 155


2x = 155 - 1


2x = 154


x = 154/2


x = 77



Hence,


The first number = x = 77


The second number = x + 1 = 77 + 1 = 78
