Use the explicit formula An=4.8+(n−1)2%0D%0A%0D%0A%0D%0A=%0D%0A4.8%0D%0A+%0D%0A(%0D%0A%0D%0A−%0D%0A1%0D%0A)%0D%0A2%0D%0A to find the 11th term in the described arithmetic sequence.
To find the 11th term in the arithmetic sequence using the explicit formula, plug in n = 11 into the formula:
A11 = 4.8 + (11 - 1) * 2
Simplify:
A11 = 4.8 + (10) * 2
A11 = 4.8 + 20
A11 = 24.8
Therefore, the 11th term in the arithmetic sequence is 24.8.
