WebCorrect option is A) Given, S n=4n 2−n When n=1 , S 1=4(1) 2−1=4−1=3 Now, obviously, the sum of the first term will be the first term itself, as there are no other terms involved. When n=2 , S 2=4(2) 2−1=16=2=14 The sum of the first 2 terms is equal to a 1+a 2 Therefore, a 1+a 2=14 We have shown, above, that a 1=3 Substituting it in a 1+a 2=14, WebAug 31, 2015 · an = 4n +5. We can find terms 1 to 5 by substituting n respectively in the expression. an = 4n +5. So, a1 = 4 ⋅ (1) + 5 = 9. a2 = 4 ⋅ (2) + 5 = 13. a3 = 4 ⋅ (3) + 5 = 17. a4 = 4 ⋅ (4) + 5 = 21. a4 = 4 ⋅ (5) + 5 = 25. most likely clip art https://dvbattery.com
