Answer 2

Answer:

common difference= -7/3

Step-by-step explanation:

let 7th term be a₇ and tenth term be a₁₀

let common difference be d and the first term of AP be a

aₙ=a+(n-1)d

a₇=a+(7-1)d= a+6d

a₁₀=a+(10-1)d=a+9d

according to the question,

a₇=a₁₀+7

ie, a+6d=a+9d+7

=9d-6d=-7

=3d=-7

=d=-7/3
