The nth term of a sequence is n 2 + 20
WebThis is the formula of an arithmetic sequence. an = a1 +d(n−1) a n = a 1 + d ( n - 1) Substitute in the values of a1 = 20 a 1 = 20 and d = −4 d = - 4. an = 20−4(n−1) a n = 20 - 4 ( n - 1) Simplify each term. Tap for more steps... an = 20−4n+4 a n = 20 - 4 n + 4 Add 20 20 and 4 4. an = −4n+24 a n = - 4 n + 24 WebFind the nth term and sum of the arithmetic sequence for 15 number of terms if the first term is 5 and the difference is 4. Solution: Step 1: Identify the values. n = 15 a = 5 d = 4 Step 2: Use the arithmetic sequence formula and place the values. For finding the nth term nth term = a + (n - 1)d = 5 + (15 - 1) × 4 = 61 n th term = 61
