How do I solve this I don't understand?

Answer:
The equation for this sequence will be 8 + 17n - 17 with n being replaced with the term number you are trying to find.
so 8 + 17(16) - 17
17 x 16= 272
8 + 272= 280
280- 17= 263
Thus, the 16th term will be 263.
Answer:
16ᵗʰ Term of the sequence is 263
Step-by-step explanation:
Here,
First Term = a₁ = 8
Second Term = a₂ = 25
Third Term = a₃ = 42
Now,
Common Difference (d)
d = a₂ - a₁ = 25 - 8 = 17
d = a₃ - a₂ = 42 - 25 = 17
Here, Common Difference is same everywhere
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 8 + (16 - 1) × 17
a₁₆ = 8 + 15 × 17
a₁₆ = 8 + 255
a₁₆ = 263
Thus, 16ᵗʰ Term of the sequence is 263
