Write the sequence of coloours in a carbon resistor having resistance `25 xx10^6 Omega pm 10 %` .

Explanation

To determine the color code for a carbon resistor with a resistance of \( 25 \times 10^6 \, \Omega \pm 10\% \), we will follow the standard color coding system for resistors. The color code consists of four bands: the first two bands represent the significant digits of the resistance, the third band represents the multiplier, and the fourth band indicates the tolerance.

### Step-by-Step Solution:

1. **Identify the Significant Digits:**
- The resistance value is \( 25 \times 10^6 \, \Omega \).
- The significant digits are 2 and 5.
