Question

253, 248 ,243 find the 49th term

Answer 1

To find the 49th term of the sequence 253, 248, 243, ... , we notice that the sequence is decreasing by 5 each time. This is an arithmetic sequence with a common difference of -5.

We use the formula for the nth term of an arithmetic sequence, which is:
nth term = first term + (n - 1) * common difference

Here, the first term is 253, the common difference is -5, and we're looking for the 49th term.

Plug these into the formula:
49th term = 253 + (49 - 1) * -5
49th term = 253 + 48 * -5
49th term = 253 - 240
49th term = 13

So, the 49th term of the sequence is 13.
