T1 equals a
T2 equals - a plus d
Therefore -d equals T2 minus T1
(solved)- d equals -x minus 1
T3 equals - a plus 2d
Recall dah T2 equals - a plus d
Therefore d equals T3 minus T2
(solved) d equals -3
Recall dah d equals -x minus 1
Therefore 3 equals x minus 1
X equals 4

he Joint Admission and Registration Board (JAMB) has announced the postponement of the 2017 UTME registration and the examination.

The JAMB Registrar disclosed this in a statement in Abuja.

According to him, the registration deadline has been shifted from April 19th to May 5th, 2017.

The 2017 UTME examination on the other hand has been shifted. It will now start from May 13 to M@ay20
....
"Instead of the earlier announced April 19, the deadline for the sale of forms and registration will now extend to Friday, May 5, 2017. Consequently, the 2017 UTME has also been postponed to start on Saturday, May 13 – 20, 2017." The JAMB Boss stated.

Sorry its a bit confusing

Smart, here's a quicker method
Since they are in arithmetical progression,
d= 2x+3 - 2x
= 3
Also d= 2x - (x+1) = x-1
.•. 3 = x-1
.•. x = 4
