Explanation:

In the given series –

If we take 701 = X

So, 349 = Y

Similarly, 173 = X

So, 85 = Y and so on -----

Now, (i) 701 = 2 ×349+3

701 = 701

If we take any term of given series, then statement (i) following

(ii) 349 = 701 ×3+2

349 ≠2105

So, statement (ii) did not follow if we take any term of the given series as ‘X’ & ‘Y’

(iii) (701 – 349) = 2 ×(349−173)

352 = 2 ×176

352 = 352

So, if we take any term of given series, then statement (iii) following
