Question

which term of the arithmetic sequences 50,53,56,....and 10,17,24,..... is equal?​

Answer 1

Answer:

11

Step-by-step explanation:

let the first term of first sequence be 'a'=50

let the common difference of the first sequence be'd'=53-50=3

let the first term of second sequence be' b'=10

let the common difference be d'=17-10=7

n be the common term

nth term of an AP =a+(n-1)d

50+(n-1)3=10+(n-1)7

50+3n-3=10+7n-7

44=4n

n=11
