Answer:
The 15th term is (x+63)
Step-by-step explanation:
Given the A.P series
x-7, x-2, x+3,......
we have to find the 15th term of A.P
An arithmetic sequence is a sequence of numbers where each number is the sum of previous number and a constant, called the common difference.
\text{Common difference=}d=x-2-(x-7)=x-2-x+7=5
x-7, x-2, x+3,......
a=x-7, d=5, n=15
The recursive formula for A.P is
a_n=a+(n-1)d
a_{15}=x-7+(15-1)5
a_{15}=x-7+70
a_{15}=x+63
Hence, the 15th term is (x+63)
