17th term = a + (n -1)d
= a + (17 - 1)d = a + 16d
10th term = a +(n - 1)d
= a + (10 - 1)d = a +9d
now,
17th term - 10th term = 7
a + 16d - (a + 9d) = 7
a + 16d - a -9d = 7
7d = 7
d = 1
= a + (17 - 1)d = a + 16d
10th term = a +(n - 1)d
= a + (10 - 1)d = a +9d
now,
17th term - 10th term = 7
a + 16d - (a + 9d) = 7
a + 16d - a -9d = 7
7d = 7
d = 1
