From the image, the problem seems to ask you to find the value of $a_{50}$ using the values of $a_1$ and $S_{50}$.

The given information appears to be:

• $a_1 = 6$
• $S_{50} = 6650$
• The formula for the sum of the first $n$ terms of an arithmetic series is $S_n = \frac{n}{2} (a_1 + a_n)$.

Using this formula for $S_{50}$:

$S_{50} = \frac{50}{2} (a_1 + a_{50})$

Substitute the given values $a_1 = 6$ and $S_{50} = 6650$ into the equation:

$6650 = \frac{50}{2} (6 + a_{50})$

Now, let's solve for $a_{50}$.

$6650 = 25 (6 + a_{50})$ $\frac{6650}{25} = 6 + a_{50}$ $266 = 6 + a_{50}$ $a_{50} = 266 - 6$ $a_{50} = 260$

Thus, the value of $a_{50}$ is 260.
