Ответ:
an = (2n-1) + a(n-1)
a1 =1
Step-by-step explanation:
a1 =1
a2 = 4
a3 = 9
We can see that the number of boxes is the term number squared
an = n^2 is the explicit formula
an = (2n-1) + an-1
a1 =1
Check
a1=1
a2 = (2*2-1)+1 =3+1 =4
a3 = (2*3-1)+4 =5+4 =9
a4 = (2*4-1)+9 =7+9 =16

Step-by-step explanation:
Let the box be x
x¹ = 1
x ² = 4
x³ = 9
Here, we can notice that the no. of boxes are in the term of square .
x n = (2n-1 ) + an - 1 is the formula
x ¹ = 1
x ² = (2 × 2 - 1) + 1 = 4
x ³ = ( 2 ×3 -1 ) + 4 = 9
x ⁴ = ( 2 × 4 - 1 ) + 9 = 16
