Oliver and putri were asked to find an explicit formula for the sequence -51,-34,-17, oliver said the formula is h(n)=-51+17n. putri said the formula is h(n)=-68+17n. which one of them is right?

Putri is correct

This is an arithmetic sequence, whose n th term is

= + (n - 1 )d

where is the first term and d the common difference

d = - 17 - (- 34 ) = - 34 - (- 51) = 17 and = - 51, hence

= - 51 + 17(n - 1) = - 51 + 17n - 17 = 17n - 68 ← Putri

this doesn't make sense lol

the answer is simply just 6n add the two together as they have an n
