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,
[tex]T_n=a_1+(n-1)d[/tex]
Here, n = number or term
We have to calculate 15th term of the sequence,
[tex]T_{15}=-20+(15-1)(4)[/tex]
= -20 + 56
= 36
Therefore, 15th term of the sequence is 36.
