Answer: 560
Step-by-step explanation: i had this exact question on OW
Answer:
a₅₃ = 560
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = - 12 and d = a₂ - a₁ = - 1 - (- 12) = - 1 + 12 = 11 , then
a₅₃ = - 12 + (52 × 11) = - 12 + 572 = 560
