Question

Th term of the sequence 23, comma, 19, comma, 15, comma, point, point, .23,19,15,

Answer 1

The 15th term of the sequence 23, 19 15,... is -33.

What is the 15th term of the sequence?

23, 19, 15......

First term, a = 23

Common difference, d = Second term - first term

= 19 - 23

= -4

15th term= a + (n - 1)d

= 23 + (15 - 1)-4

= 23 + (14)-4

= 23 + (-56)

= 23 - 56

= -33

Hence, 15th term equals negative 33
