You could do something like this:

seed = 2
tuple(seed * 10**n for n in range(4))

Given a seed it will create a list of seed * 1, seed * 10, seed * 100, etc. and then cast that as a tuple

You could use tail recursion (although tail recursion within python doesn't add much of a benefit):

tuple = (2, )
n = 4
def generate(n, tuple):
    if n == 1:
        return tuple
    else:
        tuple = tuple + (tuple[-1]*10, )
        return generate(n-1, tuple)

print(generate(n, tuple))

Output:

>> (2, 20, 200, 2000)

Something like this would work: 

tuple = ()
n = 5 # amount of items
num = 2 # number you want to have in the tuple
for x in range(n):
    new_item = num*10**x
    tuple += (new_item,)

print(tuple)
