Answer:
Interpreting as: X=a-sqrt b X=a+sqrt b
Input:
X = a - sqrt(b) X = a + sqrt(b)
Alternate forms:
{a = (sqrt(b) + 1) X, a = X - sqrt(b), b = 0 ∨ X = -1}
{a = (sqrt(b) + 1) X, a + sqrt(b) = X, sqrt(b) (X + 1) = 0}

Answer:
46 terms
Step-by-step explanation:
a₁=b, a₂₁= bₙ, d₁=9, d₂=4
n=?
---------------
a₂₁= a₁+20d₁= a₁+20*9= a₁+180
bₙ= b₁+(n-1)d₂= a₁+4(n-1)
a₁+4(n-1)=a₁+180
4(n-1)=180
n-1= 180/4
n-1= 45
n=46
