a. Write the arithmetic sequence with first term 2 and common difference 3. b. Check whether 100 is a term in this sequence. c. Check whether the difference of any two terms of this sequence will be 2015. d. Find the position of the term 125 in this sequence. |

Answer» a. f = 2 d. = 3 Sequence is 2, 5, 8, 11, ………. b. If (100 – 2) is not a multiple of common difference 3, then 100 is not a term of the arithmetic sequence. c. 2015 is not a multiple of common difference 3, so 2015 will not be the difference of any two terms of this sequence. d. xn = 3n – 1 3n-1 = 125 3n = 126 n = 42 |
