Step-by-step explanation:
17th term exceeds it's 10th term by 7
a+16d = (a+9d) + 7
a + 16d = a + 9d + 7
a will cancel out.
16d = 9d + 7
16d - 9d = 7
7d = 7
d = 7/7
d = 1

Step-by-step explanation:
17th term means a17
10th term means A10
so a17= A10+7
a+16d=a+9d+7
a+16d-a-9d=7
a gets cancelled
16d-9d=7
7d=7
d=7/7
d=1
