Answer:
the answer should be B
Step-by-step explanation:
the first part is basically finding the difference between the terms, as we know that d=T2-T1
so by comparing the T2-T1 and T3-T2 we can find the difference with the two variables h and k
afterwards do the same with T4-T3 and T3-T2, comparing them and you will get another equation
now that you have two equations, you can do simultaneous equation to get the answers
hope i helped :D
