Question

The end term of an ap is N is equal to 4 and + 5 then the fifth term is

Answer 1

Answer:

an = a + (n − 1) × d

Explanation:

• Common Difference in Arithmetic Progression
• In this progression, for a given series, the terms used are the first term, the common difference between the two terms and nth term. Suppose, a1, a2, a3, ……………., an is an AP, then; the common difference “ d ” can be obtained as;
• d = a2 – a1 = a3 – a2 = ……. = an – an – 1
• Where “d” is a common difference. It can be positive, negative or zero.
• First Term of AP
• The AP can also be written in terms of common difference, as follows;
• a, a + d, a + 2d, a + 3d, a + 4d, ………. ,a + (n – 1) d
• where  “a” is the first term of the progression.
