Thabit: Thabit numbers

Description

Under OEIS A055010, the nth Thabit number is given as $$A_n = 3*2^{n-1}-1$$ where the first 6 entries are 0, 2, 5, 11, 23, 47 with \(A_0 = 0.\)

Usage

Thabit(n, Rmpfr = TRUE, PrecisionBits = 496)

Arguments

n

the number of first n entries from the sequence.

Rmpfr

a logical; TRUE to use large number representation, FALSE otherwise.

PrecisionBits

a positive integer for precision bits larger than 2.

Value

a vector of length n containing first entries from the sequence.

Examples

# NOT RUN {
## generate first 30 Thabit numbers
first30 = Thabit(30)

## print without trailing 0's.
print(first30, drop0trailing = TRUE)

# }
