Question

Observe the following pattern and answer the questions that follow :
1 + 2 + 3 + 4 + 5 = 15
2 + 3 + 4 + 5 + 6 = 20
3 + 4 + 5 + 6 + 7 = 25
(1) By which number should we multiply the middle number to get the sum?
(1) Write the row of the pattern which gives the sum as 75.
(1) Can there be any row of the pattern which gives the sum as 92?​

Answer 1

Answer:

(1) 5

(2)13+14+15+16+17 = 75

(3)No

Answer 2

The given question

1 + 2 + 3 + 4 + 5 = 15

2 + 3 + 4 + 5 + 6 = 20

3 + 4 + 5 + 6 + 7 = 25

based on the above observation there are certain questions to be answered.

They are

(1) By which number should we multiply the middle number to get the sum?

In the above 3 series the result or the sum is the multiple of the middle number in the series.

which is

3*5=15

4*5=20

5*5=25

Therefore, the answer is 5

(2) The row of pattern that gives the sum as 75 is

13+14+15+16+17=75

(3) Can there be any row of the pattern which gives the sum as 92?

No, there is no row of pattern that gives the sum as 92.

Therefore, the above questions are answered.
