Answer :
Answer:
99
Step-by-step explanation:
50 = 7(7) + 1
155 = 7(22) + 1
218 = 7(31) + 1
288 = 7(41) + 1
Numbers inside ( )
7, X, 22, 31, 41
X = 14
Missing term = 7(14) + 1 = 99
The missing number in the sequence 50, ?, 155, 218, 288 is approximately 130, based on the average differences between terms. This sequence is increasing non-linearly. The pattern suggests adding about 80 to the previous number.
To find the missing number in the sequence 50, ?, 155, 218, 288, we need to identify the pattern. Let's calculate the differences between consecutive terms:
- 155 - 50 = 105
- 218 - 155 = 63
- 288 - 218 = 70
The differences are 105, 63, and 70. These do not form a simple arithmetic or geometric progression, so let's consider the average of the differences:
- (105 + 63 + 70) / 3 = 79.33
This suggests the series might involve complex calculations or be non-linear. However, a reasonable assumption based on the increasing differences is approximately 80. Adding 80 to 50 yields approximately:
- 50 + 80 = 130
Therefore, the missing number is approximately 130.
