Answer:
a₇₀ = 1122
Explanation:
Taking it you mean the 70th term of the arithmetic sequence.
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
a₁ is the first term , d the common difference , n the term number
here a₁ = 18 and d = a₂ - a₁ = 34 - 18 = 16 , then
a₇₀ = 18 + (69 × 16) = 18 + 1104 = 1122
