The sequence 1, 4, 13, 40, 121 can be described by a recursive formula. The recursive relationship can be expressed as ( a_n = 3a_{n-1} + 1 ) for ( n \geq 2 ), with the initial condition ( a_1 = 1 ). This means each term is generated by multiplying the previous term by 3 and then adding 1.

To get the next term, triple the present term and add 1 . The next term after 40 is 121 .

To get the next term, triple the present term and add 1 . The next term after 40 is 121 .
The factors of 121 are 1, 11, 121 The factors of 280 are 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1,093 3,2804 - 1 = 313 - 4 = 940 - 13 = 27121 - 40 = 81364 - 121 = 243each difference is 3 times the previous243 x 3 = 729 then 364 + 729 = 1,093729 x 3 = 2,187 then 1,093 + 2,187 = 3,280
121/40
121 divided by 3 equals 40 with a remainder of 1.
The number is 55+66 = 121
42 + 79 = 121 (40+70) + (2+9) = = 110 + 11 = 121
