Question

Find the 8th term of the arithmetic sequence.
a1 = 20, d = 5

Answer 1

the answer is 55

Answer 2

The answer is 55

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
