Step-by-step solution

To find the eighth element of the sequence defined by the formula n2 \frac{n}{2} , we will follow these steps:

  • Identify the formula provided for the sequence: an=n2 a_n = \frac{n}{2} .
  • Determine the position in the sequence we need: n=8 n = 8 .
  • Substitute n=8 n = 8 into the formula to find a8 a_8 .

Substituting n=8 n = 8 into the formula, we have:

a8=82 a_8 = \frac{8}{2} .

This simplifies to a8=4 a_8 = 4 .

Therefore, the eighth element of the sequence is 4 4 .
