Trevor says If $u_1 = 3.75$ then $u_{100} = 3.75$ - OCR - GCSE Maths - Question 14 - 2019 - Paper 1

To verify Trevor's statement, we need to analyze the sequence defined by the relation given. If the sequence is constant such that each term is equivalent to the first term, then indeed, if $u_1 = 3.75$, it follows that $u_n = 3.75$ for any term in the sequence.

Assuming $u_n$ is a constant sequence, we can denote this as: $u_n = u_1 = 3.75 ext{ for all } n$ Therefore, $u_{100} = 3.75$ is true under this assumption.
