make a conjecture (obsevations based on patterns) for each sequence below.
a)7,10,13,16
b)4,44,444,4444,44444
c)2,10,50,250
d)1,2,6,42,1806,3263442

i got some of them but i think they need to be writen better
a)Add three to each number to get the next number in the sequence.
b)?(cant put it into words)
c)starting with two and going up by multiplying each new # by 5
d)is like 1*2=2, 2*3=6, 6*7=42, 42*43=1806, 1806*1807=3263442 (but i cant put that into words)

1. b) Add the digit, 4, to each preceding number.

d) The multiplier is one more than the preceding product.

Evaluate the following sums: 1 1+8 1+8+27 1+8+27+64 Add two more line to the list, and make a conjecture about the sums you obtained. this is a pattern. if you look closely than you'll see each number is a product of another

Make a conjecture about the next item in each sequence. 1.4,6,9,13,18 -I know that from 4 to 6 they added 2 and then from there each time the number you add is 1 more than the last one, but I don't know how to make a conjecture.
