SOLUTION:
0.6 + 0.06 = 0.66
0.66 + 0.06 = 0.72
OR
0.66 - 0.6 = 0.06
0.72 - 0.66 = 0.06
Therefore, the numbers are increasing by 0.06
Thus, in order to obtain the next number in the pattern, I will add 0.06 to the currently last number in the patter as displayed below:
0.72 + 0.06 = 0.78
FINAL ANSWER:
Therefore, the next number in the pattern is 0.78.
Hope this helps! :)
Have a lovely day! <3
