Answer:

a₇₀ = 1122

Explanation:

Taking it you mean the 70th term of the arithmetic sequence.

The nth term of an arithmetic sequence is


a_(n) = 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
