Question

The pattern below follows the rule, "starting with a value of 3, everyconsecutive row has a value that is 2 less than twice the value of the previousrow."ValueRow 13Row 24Row 36What is the value for the 5th row?O A. 66B. 34O C. 18OD. 12

Answer 1

Given,

The data of the three rows is 3, 4, 6.

The formula for the insertion of data in successive row is,

`\text{ }successive\text{ = 2 previous term -2}`

The number at row 4 is,

`\text{ forth row value = 2}*6\text{ -2}=10`

The number at row 5 is,

`\text{ fifth row value = 2}*10\text{ -2}=18`

Hence, the value at fifth row is 18.
