Let's try and see what is the pattern that we have:
Sum of first odd number is 1²
Sum of first 2 odd numbers is 2² (1 + 3 = 4)
Sum of first 3 odd numbers is 3² (1 + 3 + 5 = 9)
Sum of first 4 odd numbers is 4² (1 + 3 + 5 + 7 = 16)
I think you would have been able to see the pattern now.
As a result,
Sum of first 7 odd numbers will be 7² = 49
