for the arthmectic sequence 5, 7, 9, ...... find A is it 21 17 19 or 12

1 answer

To find the value of A in the arithmetic sequence 5, 7, 9, ..., we first need to determine the common difference between consecutive terms.

The common difference can be found by subtracting the first term from the second term:
7 - 5 = 2

Since each term in the sequence is increasing by 2, we can find the value of A by adding this common difference to the last given term:

9 + 2 = 11

Therefore, the value of A is 11.
