Hi Friend ✋✋
a10 = a + 9d = 41 .........(1)
a18 = a + 17d= 72.........(2)
(1) - (2)
a - a + 9d - 17d = 41 -73
8d = 32
d = 4
a + 36 = 41
a = 5
then a26 = 5 + 25 × 4 = 5 + 100 = 105
hope it helps

"The 26th term will be 105.
Given:
10th term = a + 9d = 41
18th term = a + 17d= 72
To find:
26th term
Solution:
10th term = a + 9d = 41 .........(1)
18th term = a + 17d= 72 .........(2)
(1) - (2)
a - a + 9d - 17d = 41 -73
8d = 32
d = 4
a + 36 = 41
a = 5
then the 26th term will be
26th term = a+25d
Then the 26th term will be 105."
