Explanation

The sequence follows the pattern: 35, 35+13=48, 48+51=99, 99+21=120, 120+75=195, 195+39=234. The differences are 13, 51, 21, 75, 39. This does not show a clear pattern. Checking n^3-n or similar: 3^3+8=35, 4^3-16=48, 5^3-26=99, 6^3-96=120... The term 234 is often cited in this sequence as the outlier.

AI explanation

The sequence is built by adding consecutive squares of prime numbers to the previous term, starting with 35 plus 13 equals 48. However, a more apparent pattern is that the sequence is formed by the product of consecutive numbers added to another specific number, such as 4*8+3=35. The differences are 13, 51, 21, 75, and 39, and the correct sequence should yield 224 as the last term instead of 234; therefore, 234 is the wrong term.
