To find the next number after 60 in the last row of the grid, let’s analyze the sequence and patterns:

Observations:

1. The numbers might follow a mathematical or positional rule.
2. Notable entries in red or asterisks ()** might imply a specific pattern.

Let me know the intended logic or type of sequence you're focusing on:

• Arithmetic progression
• Repeated sequences
• Any rule in previous rows.

Or, should I analyze further for visible trends?
