Study the pattern.1 × 8 + 1 = 9 12 × 8 + 2 – 98 123 × 8 + 3 = 987 1234 × 8 + 4 = 9876 12345 × 8 + 5 = 98765Write the next four steps. Can you find out how the pattern works?

Answer»

12 × 8 + 2 = 98 

123 × 8 + 3 = 987

1234 × 8 + 4 = 9876 

12345 × 8 + 5 = 98765 

123456 × 8 + 6 = 987654 

1234567 × 8 + 7 = 9876543 

12345678 × 8 + 8 = 98765432 

123456789 × 8 + 9 = 987654321

The digits on the L.H.S. are in increasing order and the digits on the result (right side) are in decreasing order.
