Answer:
1,4,9,16,25,36,49
Step-by-step explanation:
The pattern is :
1,4,9,16,_,_,_,...
First no is 1
Second no is 4
Third no is 9
Fourth no is 16
Difference between second and first no. = 4-1 = 3
Difference between third and second no. = 9-4= 5
Difference between fourth and third no. = 16-9 = 7
Fifth no is :
16 + 9 = 25
Sixth no is : 25 + 11 = 36
Secenth no. is : 36 + 13 = 49
Hence, the pattern is :
1,4,9,16,25,36,49
