Narwal4u · Answer

A geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous number.
If we use this we can see that if the first number is 4 lest then the less number then you would have to add 4 to each one.
Answer: 1, 3, 7, 8

thank you

teressa1246 · Answer

so you would sub the first 2 numbers and than add it to the rest of the numbers
