In an ap a is equal to 5 by 2D is equal to 3 by 2 SN is equal to 195 n...
Given Information:
- a = 5
- 2D = 3
- SN = 195
Finding n:
- Since a = 5, we can write a as a = 2D - 1. This implies 5 = 2(3) - 1 = 6 - 1 = 5.
- Therefore, D = 3/2.
Finding n using the formula for the sum of n terms in an AP:
- SN = n/2 [2a + (n-1)d]
- Substituting the values we have: 195 = n/2 [2(5) + (n-1)(3/2)]
- Simplifying the equation: 195 = 5n + (3n - 3)/2
- Solving for n, we get n = 20.
Therefore, the values of n and a are:
- n = 20
- a = 5
- a = 5
- 2D = 3
- SN = 195
