Question

If a1= -3 and d =2, write the explicit formula of the arithmetic sequence

Answer 1

Answer:

Answer: The explicit formula for the given expression is 2 n - 3 Step-by-step explanation: Here, the first term of sequence = -1 The common difference = 2 In a ARITHMETIC PROGRESSION: The nth term of a sequence is given as a(n) = a + (n-1) d ⇒ Here, a(n) = -1 + (n-1)(2) = -1 + 2n -2 = 2n - 3 or, a(n) = 2n - 3 Hence, the explicit formula for the given expression is 2n - 3.
