Question

find the first term ,common difference and given terms in arithmetic progression
1) 1, 3by2, 2, 5by2, 3, 7by3..(10th term)
2)x,2x,3x,4x...(25th term)
​

Answer 1

Answer:

1.

first term =1

common difference= (3/2)-1. = 1/2

10th term = 1+(9*(1/2)) = 11/2

2.

first term = x

common difference = 2x-x = x

25th term = x+(24*x) = 25x
