Question

The following pattern shows how to multiply any number by $5, 15$ and $25$ . Study the pattern. Write the next three steps.
$86 x 5 = 86 x \frac{10}{2} = 43 x 10 = 430 x 1 86 x 15 = 86 x \frac{30}{2} = 43 x 30 = 430 x 3 86 x 25 = 86 x \frac{50}{2} = 43 x 50 = 430 x 5$

Solution

Given
$86 x 5 = 86 x \frac{10}{2} = 43 x 10 = 430 x 1 86 x 15 = 86 x \frac{30}{2} = 43 x 30 = 430 x 3 86 x 25 = 86 x \frac{50}{2} = 43 x 50 = 430 x 5$
The next three steps are
$86 \times 35 = 86 \times \frac{70}{2} = 43 \times 70 = 430 \times 7 86 \times 45 = 86 \times \frac{90}{2} = 43 \times 90 = 430 \times 9 86 \times 55 = 86 \times \frac{110}{2} = 43 \times 110 = 430 \times 11$
Hence, the next three steps are as mentioned above.
