Answer:
sequence 12,19,26,33
1st term = 12
comman difference = 19 - (12) = 7
comman term = a + (n-1)d
a= first term
d= difference
comman term = a + (n-1)d
= 12 + (n-1)(7)
= 12 +7n-7
= 7n +5
1st term --> n =1 = 7.1 + 5 = 12
2nd term --> n =2 = 7.2 + 5 = 14 + 5 = 19
64st term --> n =64 = 7.64+ 5 = 448+5 = 453
