Solution 3(1):
Product of the first and the fourth term = 2 × 49 = 98
Product of the second and the third term. 7× 14 = 98
Product of the first and the fourth term = Product of the second and the third term = 98
Hence, 2, 7, 14, 49 are in proportion.
Solution 3(2):
Product of the first and the fourth term = 3 × 35 = 105
Product of the second and the third term. 21× 5 = 105
Product of the first and the fourth term = Product of the second and the third term = 98
Hence, 3, 21, 5, 35 are in proportion.
Solution 3(3):
Product of the first and the fourth term = 2 × 11 = 22
Product of the second and the third term. 11× 4 = 44
Product of the first and the fourth term ≠ Product of second and third term
Hence, 3, 21, 5, 35 are not in proportion.

Solution 1:
Product of the first and the fourth term = 3 × 21 = 63
Product of the second and the third term. 7 × 9 = 63
Product of the first and the fourth term = Product of second and third term = 63
Hence, 3, 7, 9, 21 are in proportion.
Solution 2:
Product of the first and the fourth term = 7 × 13 = 91
Product of the second and the third term. 6 × 12= 72
Product of the first and the fourth term ≠ Product of the second and the third term
Hence, 7, 6, 12, 13 are not in proportion.
Solution 3:
Product of the first and the fourth term = 4 × 20 = 80
Product of the second and the third term = 8 × 10 = 80
Product of the first and the fourth term = Product of the second and the third term = 80
Hence, 4, 8, 10, 20 are in proportion.
Solution 4:
Product of the first and the fourth term = 10 × 24 = 240
Product of the second and the third term. 15 × 16 = 240
Product of the first and the fourth term = Product of the second and the third term = 240
Hence, 10, 15, 16, 24 are in proportion.
Solution 5:
Product of the first and the fourth term = 25 × 50 = 1250
Product of the second and the third term = 30 × 40 = 1200
Product of the first and the fourth term ≠ Product of the second and the third term
Hence, 25, 30, 40, 50 are not in proportion.
Solution 6:
Product of the first and the fourth term = 9 × 21 = 189
Product of the second and the third term. 11 × 20 = 220
Product of the first and the fourth term ≠ Product of the second and the third term
Hence, 9, 11, 20, 21are not in proportion.
