Answer:

62 squares is correct

Explanation:

The pattern is increasing by 3 each time.

The pattern is progressing arithmetically

The nth term of an arithmetic progression is


a_(n) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 5 and d = 3 , then


a_(n) = 5 + 3(n - 1) = 5 + 3n - 3 = 3n + 2

Then

a₂₀ = 3(20) + 2 = 60 + 2 = 62
