Answer:
1376
Step-by-step explanation:
In an arithmetic sequence, each term is larger than the previous one by a common difference, d.
In your sequence,
a₂ - a₁ = 26 - 8 = 18
a₃ - a₂ = 44 - 26 = 18
The common difference between successive terms is 18, so
d = 18
The formula for the nth term of an arithmetic sequence is
aₙ = a₁ + (n - 1)d
If n = 77, the formula becomes
a₇₇ = 8 + (77 - 1) × 18 = 8 + 76 × 18 = 8 + 1368 = 1376
The 77th term of your sequence is 1376
