Question

Find the 24th term.
-21, -14, -7, 0, 7, ​

Answer 1

Step-by-step explanation:

all you have to do is keep adding a positive 7 until you get 24 total whole numbers

-21,-14,-7,0,7,14,21,28,35,42,49,56,63,70,77,84,91,98,105,112,119,126,133,140,147,154,161,168.

Answer 2

To find the 24th term, use the formula nthTerm = firstTerm + (n - 1) * commonDifference.

Step-by-step explanation:

To find the 24th term, we can observe that the sequence is increasing by 7 each time. So, we can create an arithmetic sequence with the first term -21 and common difference 7.

The formula for finding the nth term of an arithmetic sequence is: nthTerm = firstTerm + (n - 1) * commonDifference.

By substituting the values into the formula, we can find the 24th term: nthTerm = -21 + (24 - 1) * 7 = -21 + 23 * 7 = -21 + 161 = 140.
