Question

Use the explicit formula an = a1+(n-1) * d to find the 350th term of the sequence below. 57, 66, 75, 84, 93,...

Answer 1

a₃₅₀ = 3198

Explanation:

given the explicit formula

`a_(n)` = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 57 and d = a₂ - a₁ = 66 - 57 = 9 , then

a₃₅₀ = 57 + (349 × 9) = 57 + 3141 = 3198
