How do you work out the 50th term of anything?

To find the 50th term of a sequence, you typically need the formula or rule governing the sequence. If it's an arithmetic sequence, use the formula ( a_n = a_1 + (n-1)d ), where ( a_1 ) is the first term, ( d ) is the common difference, and ( n ) is the term number. For geometric sequences, the formula is ( a_n = a_1 \times r^{(n-1)} ), where ( r ) is the common ratio. Substitute ( n = 50 ) into the appropriate formula to calculate the 50th term.
