Question

The sum of the first three terms of A.P is 18 if the first term is 4 find their product​

Answer 1

Answer:

192

Step-by-step explanation:

The sum of the first 3 terms of the A. P is

a + a + d + a + 2d = 18, that is

3a + 3d = 18 ← substitute a = 4

12 + 3d = 18 ( subtract 12 from both sides )

3d = 6 ( divide both sides by 3 )

d = 2

Thus the first 3 terms are

4, 6, 8 and their product = 4 × 6 × 8 = 192

Additional Information :

• Arithmetic progression (A.P.) is a sequence in which each term can be found by adding a certain quantity to its preceding term
• Difference between two consecutive terms is called common difference
• Progression means it's a type of sequence in which each term is related to its predecessor and successor.
