Answer:
103
Step-by-step explanation:
appears to be an arithmetic sequence question where sequence is 7, 13, 19 meaning the initial value is 7 and the common difference is 6 so we'll plug into this formula:
= 7 + (17 - 1) · 6

= 7 + 96
'7' because that's the initial value
'6' because that the common difference
'17' because that's the position the question is asking
