Step-by-step explanation:
Given that the nth term of this sequence is 5n - 3, it means we can find the terms of this AP just by replacing that terms' numeric place by n.
Suppose if we are said to find the 2nd term of this AP, then n will be replaced by 2, so 2nd term should be 5( 2 ) - 3 = > 6 - 3 = > 3
In the same manner,
= > 3rd term = 5n - 3 for n = 3
= > 5th term = 5n - 3 for n = 5
Therefore,
= > 5th term - 3rd term
= > [ 5( 5 ) - 3 ] - [ 5( 3 ) - 3 ]
= > [ 25 - 3 ] - [ 15 - 3 ]
= > 22 - 12
= > 10
