Answer:

The answer is 55

Step-by-step explanation:

Given;

  • First term (a₁) = 20
  • Common Difference (d) = 5
  • n = 8

To Find;

  • Eighth term (a₈) = ?

Formula;

  • aₙ = a₁ + (n – 1) × d

Now,

aₙ = a₁ + (n – 1) × d

a₈ = 20 + (8 – 1) × 5

a₈ = 20 + 7 × 5

a₈ = 20 + 35

a₈ = 55

Thus, The 8th term of the arithmetic sequence is 55
