65 – 47 = _____

Accepted Answer

Check: 47 + 18 = 65NCERT Textbook Pages 45-46Sums of Consecutive NumbersNumbers that follow one another in order : without skipping any number are called consecutive numbers. Here are some examples—

Question 14

In each of the boxes above, state whether the sums are even or odd. Explain why this is happening.

Accepted Answer

Box 1: Since, even + odd = odd. Here one number is odd and other is even. So, all sums are odd.Box 2: Sum of 3 consecutive numbers can be even-odd-even or odd-even-odd. Their sum alternate between even and odd depending on the starting number.Box 3: The sum of four consecutive numbers i always gives an even number because the total of two odd numbers + two even numbers is always even. So, all sums are even.

Question 15

What is the difference between two successive sums in each box? Is it the same throughout?

Accepted Answer

Box 1: 5 – 3 = 2; 7 – 5 = 2; 9 – 7 = 2.Here, the difference between two successive sums is always 2. Yes, the difference is same throughout.Box 2: 9 – 6 = 3; 12 – 9 = 3; 15 – 12 = 3.Here, the difference between two successive sums is always 3. Yes, the difference is same throughout.Box 3: 14 – 10 = 4; 18 – 14 = 4; 22 – 18 = 4.Here, the difference between two successive sums is always 4. Yes, the difference is same throughout.
