How can I found how many numbers are there in a Collatz Sequence that I found?

[cananb]

I tried to find the longest starting value less than 100,000 in a Collatz Sequence. Actually, I have two questions:

1)Output is 77,031, is this correct?
2)How can I find how many elements are there in the sequence that I found?

def sequence_number(n):
term = 1
while n > 1:
    if n % 2 == 0:
        n = n/2
    else:
        n = 3 * n+1
    term += 1
return term
 
def starting_number():
t = 0
x = 1
while x < 100000:
    if sequence_number(x) > t:
        t = sequence_number(x)
        value = x
    x += 1
 
return value
 
print("It starts with the number:", starting_number())
