Question

11/1231/10Using the pattern shown above, identify the demoninator of the second term in the 7th row.i

Answer 1

Given the harmonic triangle

We will find the denominator of the second term in the 7th row.

The given are 5 rows

so, we will find the 6th row first

the 6th row will be as follows:

`(1)/(6);(1)/(30);(1)/(60);(1)/(60);(1)/(30);(1)/(6)`

And the 7th row will be as follows:

`(1)/(7);(1)/(42);.....`

So, the answer will be

the denominator of the second term in the 7th row = 42
