7. In a “prod sequence”, a number in the sequence is the product of some of the previous terms. So in a “2 prod sequence” we start with 2 numbers and then each number that follows after is the product of the previous 2 numbers.
For example 1, 2, 2, 4, 8 ……..
Similarly, where we start with the three numbers 1, 2 and 3 then a “3 prod sequence” would be
1, 2, 3, 6, 36, 648 ……
Fill in the missing numbers in the following sequences
(a) 2 prod sequence 2, 3, ,
(b) 3 prod sequence 2, 3, 3, ,
(c) 4 prod sequence 2, 3, 5, , 210
(d) 2 prod sequence
2, , , , 500
(e) 4 prod sequence
2 , 2 , , 7 , , 3528
