Q) Which of the following are APs? If they form an AP, find the common difference d and write three more terms. iii) – 1.2, – 3.2, – 5.2, – 7.2, … Ans: Here we are given a sequence and we need to determine if the sequence qualifies to be an AP or not. After
Q) Which of the following are APs? If they form an AP, find the common difference d and write three more terms. (ii) 2, 5/2 ,3, 7/2, … Ans: Here we are given a sequence and we need to determine if the sequence qualifies to be an AP or not. After that, we need to
Q) For the following APs, write the first term and the common difference: (iv) 0.6, 1.7, 2.8, 3.9,… Ans: Here we are given AP and we need to find the first term a and common difference d. Now, first term of the AP, a1 = 0.6 (by observation) Further we can see that a2 = 1.7
