A	B	C
D	E	F
G	H	I

Answer 1

A: 6^th term in the Fibonacci sequence is 8.

B: Predecessor of 2 is 1.

C: LCM of 2 and 3 is 6.

D: HCF of 6 and 20 is 2.

E: Reciprocal of `1/5` is 5.

F: Opposite number of – 7 is 7.

G: The first composite number is 4.

H: Area of square of side 3 cm is 3 × 3 = 9 cm².

I: The number of lines of symmetry of an equilateral triangle is 3.

∴ The table becomes

8	1	6
2	5	7
4	9	3

From the table, we observe that the numbers are from 1 to 9
