Answer: The first number that appears in both sequences is 28.
Step-by-step explanation:
Let's write down numbers from each of the sequences
Sequence 1) We need to start from 7 and multiply 4
7x4=28, 28x4=112
The sequence is 7,28,112...
Sequence 2) We need to start from 8 and add 5
5+8=13, 13+5=18, 18+5=23, 23+5=28
The sequence is 8,13,18,23,28...
They both have 28
Equation = 12 - -24 = ?
After keep, change, flip: 12 + 24 = ?
Answer = 36
One is going 52 and the other 64
2 (x)+2 (x+12)=232 and solve
