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)

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

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