What is the 15th term of an arithmetic progression whose first term is equal to its common difference and whose 3rd term is 9.a.45b.15c.60d.30
Question
Solution 1
The first term (a) of the arithmetic progression is equal to the common difference (d). Given that the third term is 9, we can use the formula for the nth term of an arithmetic progression:
nth term = a + (n-1)d
Substituting the given values:
9 = a + (3-1)a 9 = 2a a = 9/2 = 4.5
