If the last term is not specified, replace l by a + (n – 1)d where d is the common difference. = 2+ (15-1)*3 , = 2 + 42 = 44. Again, if a constant C is subtracted from each term, then the common difference remains unchanged and the new sum is S – nC. A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio. Your email address will not be published. According to the question, age of the eldest child = 4 + 5 * 3 = 19 yrs. Gn are said to be Geometric means in between ‘a’ and ‘b’. . B.

Example – 2: Salary of Robin, When his salary is ₹ 5,00,000 per annum for the first year and expected to receive yearly increment of 10%. If each term of an AP is multiplied by C, common difference becomes dC and the sum SC, If a constant C is added to each term of an AP the new sum is S+nC and d remains same. Example – 9: The 7th term of a G.P is eight times of fourth term. Geometric Progression is a sequence of numbers where each term is calculated by multiplying the previous one by a fixed, non-zero number called the common ratio .
