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

28 is the first number that appears in both sequences.

multiply by 4 starting from 7

  • First sequence: 7 * 4 = 28 *4 = 112 * 4 = 448

add 5 starting from 8

  • Second sequence: 8 + 5 = 13 + 5 = 18 + 5 = 23 + 5 = 28
