9-2=7, 23-9=14, 51-23=28, 107-51=56. therefore, since the next number in the sequence will be twice the previous difference, it will be 107+112 which is 219
2×2=4+5=9
9×2=18+5=23
23×2=46+5=51

To get the (mean) average, add them up and divide by 3 [since there are 3 numbers]: 12 + 16 + 23 = 51, and 51 ÷ 3 = 17.
5.167 × 107 or 5.167E7
Start by adding 7, then add 7x2, then 7x4, then 7x8, etc. 2 + (7x1) = 9 9 + (7x2) = 23 23 + (7x4) = 51 51 + (7x8) = 107 The next number is 219.
107 double difference each time 2 + 7 = 9 9 + 7 + 7 = 23 23 + 14 + 14 = 51 51 + 28 + 28 = 107
17, 31 and 23 are.

51-23 = 28
61, 23, 97, 41, 67 yes. 51, 93, 39, no.
The Highest Common Factor (HCF) of the two numbers is 3. 63/3 = 23 and 51/3 = 17.
