Question

In the following question, the wrong term and its substitution by the correct term are indicated as a pair in the four options given below. Identify the correct pair.

$24,49,99,94,15,31,59,58$

• A. $(49,47)$
• B. $(99,95)$
• C. $(49,101)$
• D. None of these

Answer 1

The correct option is B $(99,95)$

Consider the first four terms and the second four terms.
$15,31,59,58$ are related as below
$31=2\times 15+1$
$59=4\times 15-1$
$58=4\times 15-2$
Consider $24,49,99,94$
$49=2\times 24+1$
$99=4\times 24+3$
$94=4\times 24-2$
Change $99$ to $95$ and we have
$95=4\times 24-1$

The correct pair is $(99,95).$
