Question

Write an expression to describe a rule for the sequence. Then find the 100th term in the sequence. 5, 13, 21, 29, 37, 45, … (1 point)
• 8n; 800
• 8n – 3; 797
• 3n – 8; 292
• 5 + 8n; 805

Answer 1

The sequence is going up by 8 so it must be 8n followed by something. 5 is 3 less than 8 so the full expression will be 8n-3.
Therefore the answer is 8n-3; 797
