Answer 1

Answer:

15th term of the sequence is 36

Step-by-step explanation:

Given in the question,

a₁ = First term = -20

d = common difference = 4

Expression for the nth term of an arithmetic sequence is,

$T_n=a_1+(n-1)d$

Here, n = number or term

We have to calculate 15th term of the sequence,

$T_{15}=-20+(15-1)(4)$

     = -20 + 56

     = 36

Therefore, 15th term of the sequence is 36.
