Find the 10th term of A.P 2, 7, 12......... |
|
Answer» Given ap= 2,7,12....A=2Common difference=12-7=5N term an=a+(n-1)dAn10=2+(10-1)5=2+9×510th term=47 Given A.P. 2, 7, 12, ….. First term a = 2 Common difference d = 7 – 2 = 5 nth\xa0term an\xa0= a + (n – 1)d ∴ a10\xa0= 2 + (10 – 1) × 5 = 2 + 9 × 5 = 2 + 45 = 47 Hence, 10th\xa0term of given series is 47 Given A.P. 2, 7, 12, …..First term a = 2Common difference d = 7 – 2 = 5nth term an = a + (n – 1)d∴ a10 = 2 + (10 – 1) × 5= 2 + 9 × 5= 2 + 45= 47Hence, 10th term of given series 47. |
