Question

Two series I and II are given below. Each series contains one wrong term, and both follow different patterns. Use the given conditions to find the wrong term in series I.

Series I: $a$ , $b+5$ , $c+8$ , $87$, $412$, $2185$, $13326$

Series II: $b+4$ , $c+8$ , $36$, $a+50$ , $79$, $111$, $152$

Given:

The quadratic equation $10b x^2 - (21 - a)x + 3 = 0$ has roots $\frac{z}{10}$ and $\frac{y}{20}$ , where $\frac{z}{10} > \frac{y}{20}$ .
Any multiple of $y$ ends with digit zero.
$c - z = 9$ and the LCM of $z$ and $5$ is $15$.

If the wrong term of series I is subtracted from $25$, find the result.
