is it right

clamin · Answer

Oops my bad i thought its about the first one.

anonymous · Answer

answer for the second question should be 3.25

welshfella · Answer

10th term = a1 +9d
14th term  = a1 + 13d

so you need to solve the system of equation

a1 + 9d = 17
a1 + 13d = 30

Subtract the first one from the second  to eliminate a1  and solve for d
