Question

If an= -4n+14 find the 15th team ​

Answer 1

Step-by-step explanation:

an = -4n + 14

a15 = -4(15) + 14

= -60 + 14

= -46

alternative method

a1 = -4(1) + 14 = -4 + 14 = 10

a2 = -4(2) + 14 = -8 + 14 = 6

a3 = -4(3) + 14 = -12 + 14 = 2

a = 10 d = -4

15th term a + (n-1)d

a15 = 10 + (15-1)(-4)

= 10 + 14(-4)

= 10 - 56

= - 46
